422005 GIS User Group Meeting Bugzilla
Go Go BugZilla!
- MIS has recently implemented a software program
for reporting and tracking software bugs - Called BugZilla, this program is a Web Based tool
that can be used submit bug reports for software - Once a bug is reported, the person who manages
the software is e-mailed - The software bug archives can be searched to see
if this bug has already been reported and also to
check on the status of bug fixes or workarounds - All through a Web Browser interface
432005 GIS User Group Meeting Bugzilla
- BugZilla can be found at
- http//mini-me.dnr.state.mn.us/bugzilla
- Several program options
- Search Existing Bug Reports,
- Enter a new bug report
- Summary reports and charts

- Not only bugs but also enhancements
- Submit the bugs using the Commit Button
472005 GIS User Group Meeting DRS Manager
- The DRS Manager program was designed to
- help assist GIS administrators and field users
- to build and keep current remote Data
- Resource Sites. Some key features include
- Build stand-alone Data Resource Site
- Update data and applications
- Delete Data
482005 GIS User Group Meeting DRS Manager
- Pros of a stand-alone Data Resource Site
- Access to Landview and Arcview (Quick Themes) in
a non-networked location - Easy to switch back and forth between Networked
and Stand-Alone DRS - Arcview projects read DRS data regardless of
drive. (Set DRS_LOC appropriately) - Smaller, local datasets draw quicker
492005 GIS User Group Meeting DRS Manager
- Cons of a stand-alone Data Resource Site
- Dynamic data/programs go out of date
- Located in an editable location possible
corruption of data - Updating a stand-alone DRS requires access to a
networked DRS
502005 GIS User Group Meeting DRS Manager
- The DRSmanager can be found at
- \DRS\apps\drsmanager\drsmanager.exe
- Follow the five numbered steps, and
- remember, if you go back a step, you must
- redo the steps after it.
512005 GIS User Group Meeting Data Deli II
- The Data Deli II includes more data and a more
sophisticated interface for selecting and serving
data - Intended for external (non-DNR clientele)
- Data shipped in zip format via an email notice
and FTP link link remains valid for 48 hours - Unzipping data does NOT create a DRS site
522005 GIS User Group Meeting The Joy of Imagery
- 2003 FSA Air photos have been one of the most
anticipated new GIS datasets in recent memory - Generally, imagery requires large volumes of disk
space - FSA, USGS, Met Council and Resource Assessment
imagery make up over 60 of the volume in the
DNRs GIS Database - And we anticipate that we will be getting more of
it in the future! - This presents a challenge for data storage,
distribution, backup and access
532005 GIS User Group Meeting The Joy of Imagery
- One option that is emerging is a centralized
image service that can distribute imagery via the
network - Web Mapping Services or WMS
- A WMS provides imagery via a standard request
- Give me this image for this area at this
resolution
542005 GIS User Group Meeting The Joy of Imagery
- This type of service provides an image that is
optimized for web downloads - All processing is done on the Server.
- Only one file/image to deal with
- Multiple tiles are mosaiced, resampled and
delivered - The image is only as big as the viewing area in
this case the size of the view on your screen - You never see things draw tile-by-tile
- The popular TerraServer is an example of a WMS
552005 GIS User Group Meeting The Joy of Imagery
6 tiles
Notice that as the area displayed gets larger,
the draw times for the WMS layer are pretty
consistent while the draw time for the DRS layers
increases rapidly.
562005 GIS User Group Meeting The Joy of Imagery
- Overall, the larger the area viewed, the better
WMS services become
572005 GIS User Group Meeting The Joy of Imagery
- The DNR developed a WMS Client for ArcView
- Called the DNR WMS Client
- Reads OGC files to learn about WMS services
- OGC Files are found in V\DRS\APPS\WMSCLIENT
- Works just like a normal ArcView theme
- Each time you zoom, pan or change your window a
new image is requested from the WMS
582005 GIS User Group Meeting The Joy of Imagery
Add WMS Theme Button
WMS Client Menu
592005 GIS User Group Meeting The Joy of Imagery
- Add WMS Image
- Add an image specifying the OGC file
- Download WMS Tiles
- Downloads imagery at a specific cell size clipped
to a rectangle as a series of tiled images - This can be used by folks who want to go off-line
and still have high resolution data - Save WMS Image to Disk
- Saves the current image to disk
602005 GIS User Group Meeting The Joy of Imagery
- Whats Next?
- Integrate into QuickThemes
- Refine printing process
- Develop WMS Capabilities in-house
- Already exists for some data, just not FSA images
we hope to have this soon and are waiting on a
vendor to produce! - LMIC currently has a WMS that is serving FSA data
612005 GIS User Group Meeting The Joy of Imagery
- WMS Positives
- Fast Access
- Reduced costs for overhead and delivery
- More efficient management of data
- More and more WMSs are available
- Iowa, LMIC, Data Deli
- WMS Negatives
- Need relatively speedy internet access
- Dont control your own imagery
- Doesnt work when WMS is down
- Have to download lots of imagery for printing
622005 GIS User Group Meeting Internet Links
- Collection of DNR links
- Your Internet favorites folder is located under
DOCUMENTS AND SETTINGS \USERNAME\FAVORITES - Added by network folks when updating computers,
but you can also copy it into your FAVORITES
folder - Coming to network W\ drives soon
632005 GIS User Group Meeting Intranet Pages
- Intranet GIS/GPS resources can be found at
http//dnr.state.mn.us/mis/gis

- Introduction to GPS
- Division-specific training (forestry, fisheries)
- Contact your Regional GIS Coordinator with
training requests youll be added to a waiting
list and be the first notified when a new class
is offered
652005 GIS User Group Meeting File Management
- Do you know what is on your hard drive?
- When you save a file, do you know
- where you saved it
- what the file name is
- File management especially important for GIS and
GPS users (number of files and versions of those
files) - Use MY COMPUTER or Windows Explorer to manage
your files regularly
662005 GIS User Group Meeting File Management
Right click
672005 GIS User Group Meeting File Management
- Dont compress
drives to save space - Try to save data on drive other than C, as if
Windows goes bad, the C drive must sometimes be
reformatted . . . - Reminder NAS drives are NOT backed up
682005 GIS User Group Meeting File Management
- Create a folder hierarchy to contain
files - PROJECTS\REDLK
- \OHV
- \WMAs
- \data
- \maps
- \reports
69Transitioning to ArcGIS
- The DNR is using ArcView 3.x as it desktop GIS
- Many organizations we work with are moving to the
latest versions of ArcView - 8 and more recently 9
- Should you change?
- Its not an easy question to answer
70Transitioning to ArcGIS
- DNR GIS Software Policy
- Governed by the department GIS Policy and
Planning Committee - unanimous in its opinion that Arcview 8 offers
few functional advantages over Arcview 3, and
that on a cost-benefit basis, there has been very
little incentive to promote the change - ButArcView 3 will not be supported forever
- Should be around for 3-4 years
71Transitioning to ArcGIS
- To date there has been a lack of support from the
GIS section. - This is changing
- Training course development is planned
- Tools are being migrated (QuickThemes)
- Some organizations are forcing users to upgrade
- the DNR is not following that path
- No new major software development will be done in
ArcView 3.x
72Transitioning to ArcGIS
- Some Advantages
- Arcview 9 has the look and feel of a typical
Microsoft Windows program. - It has improved map symbol control and a more
flexible mapping environment. - The ArcCatalog application has nice features for
managing your personal data. - You can use data supplied directly from the
Internet - Geodatabases are a new form of storing spatial
data. - On the fly projections
- DNR Quick Themes for Arcview 9 has some nice
enhancements over the Arcview 3 version.
73Transitioning to ArcGIS
- Some Disadvantages
- Arcview 9 is slower than Arcview 3 and requires
more computing power. - You may have to buy a new computer
- Many users consider Arcview 9 to be less stable
than Arcview 3 (freezes or locks up more) - A lot of the custom DNR tools will be unavailable
for the foreseeable future. - Large tiled, non-image data sets may not work
very well in Arcview 9 (slow draw times). - You will be limited to one layout document per
Arcview project. - You will be required to pay year maintenance fees
74Transitioning to ArcGIS
Operating the software below the minimum
specifications will result in a desktop that
crashes or locks up more than usual.
Â
75Transitioning to ArcGIS
- Cost Considerations
- 225 to convert an ArcView 3.x License to 9
- 225 Annual Maintenance fee
- Maintenance entitles you to free upgrades
- If you dont pay now, you pay later.
- Unconfirmed reports of the maintenance rising to
350.00 in 2005 - Requires you to stop using ArcView 3.x after one
year
76Transitioning to ArcGIS
- ArcGIS has three levels of software
- Arc/Info Full software implementation
- ArcEditor Edit and Create Geodatabases
- ArcView -
- Costs go down as you move from Arc/Info to
ArcView and so does cost - Extensions are available at extra cost
- Spatial Analyst
- 3D Analyst
- Network analyst
- Others.
77Transitioning to ArcGIS
- ArcView 9 purchases should be coordinated through
MIS/GIS - At this time, budgeting for on-going maintenance
will be through your division - For more information contact
- Robert Maki
- Tim Loesch
- Regional or Division GIS Coordinators
78Transitioning to ArcGIS
- ArcGIS consists of three modules
- ArcCatalog To manage spatial Data and
attributes - ArcMap Interactive map display and cartographic
output. - ArcToolBox Geoprocessing tools
792005 GIS User Group Meeting Field Data Collection
- See the Powerpoint presentation entitled
HANDHELD_COMPUTERS.PPT
802005 GIS User Group Meeting GPS Background Maps
You can use DNR GIS data to create background
maps for your Garmin Map GPS
812005 GIS User Group Meeting GPS Background Maps
- The uploading capability DNRGarmin provides
allows some mapping capabilities in all Garmins,
but there are drawbacks for storing reference
data as waypoints or tracks - Limited amount of storage, especially for
detailed line and polygon data - Little control of the display in GPS, especially
when adding numerous types of data to reference - Uploaded waypoint and track data takes up space
that may be needed for data collection - Constantly uploading and downloading data used
for reference in the field can take up a lot of
time
822005 GIS User Group Meeting GPS Background Maps
- MapSource background maps can be purchased/used,
but they dont provide the detail that DNR data
can - Tim Loesch researched a background map solution
-- a set of shareware programs on the internet - Cgpsmapper
- GPSMapEdit
- GPSSendMap
832005 GIS User Group Meeting GPS Background Maps
- GPSMapEdit program creates Garmin background maps
from ArcView shapefiles - Background maps have several advantages over GIS
data that is uploaded as waypoint or tracks - Store larger, more detailed GIS data sets (i.e.
FIM Inventory) as rather than generalizing
(smoothing) track data - Load as many background layers as you wish up to
GPS storage limits - Turn display of map layers on and off in GPS
- Use different point, line or polygon symbology
for background maps and create labels that can be
turned on and off in GPS - Still cant load raster data into GPS (i.e. FSA
photos and PRIM maps)
842005 GIS User Group Meeting GPS Background Maps
Compatible GPSs below (also the GPSIII Plus, GPS
12 map)
852005 GIS User Group Meeting GPS Background Maps
- Uploading smaller GIS datasets as waypoints or
tracks through DNRGarmin for navigation is
easier, especially for GIS data that is updated
more frequently - Background maps only work with Garmin Map GPS
models - If you need to load large GIS datasets to
reference on the GPS in the field, use background
maps - If wanting to view background map photos, youll
need to spend some more money to get a tablet PC,
or some kind of handheld computer with GIS and
GPS capabilities
862005 GIS User Group Meeting GPS Background Maps
- Documentation for the GPSMapEdit software is
currently not up to par for most GIS users - GPSMapEdit is cumbersome easier to get input
from you, the user, then hand off the development
of background maps to MIS and Division GIS
specialists - Creating background maps as standard layers to be
shared among DNR users needs some coordination
were addressing that soon
872005 GIS User Group Meeting GPS Background Maps
- A single background map can be made up of a
combination of point, line, and polygon features
along with labels and symbology for each feature
type (resulting map can resemble a PRIM map) - Keeping feature types as separate background maps
may be best -- it gives the user more options for
displaying certain features, just as if they were
turning on/off GIS layers and labels in ArcView
or Landview
882005 GIS User Group Meeting GPS Background Maps
- Two flaws have been encountered when creating
background maps from polygon features - Outlines of polygon features seem to disappear
when displaying the background maps in the GPS - Island or holes in polygon features seem to cause
problems when creating polygon backgrounds - To resolve missing polygon boundaries, outlines
are turned into line features, then lines can be
labeled - Using polygon features in background maps is
still useful to display interactive labels for
features - Holes that fill when importing polygon features
into the MapEdit program can be refreshed so
they no longer appear as part of the polygon
892005 GIS User Group Meeting GPS Background Maps
- Labels can obscure the view of features in
background maps, especially if they long - Labels can be turned off or set to appear
interactively within the Map Setup options - To create maps that will be used as label
background maps by using point and/or polygon
features - Create centroid points to be used as labels for
line features such as roads or trails if their
density prohibits viewing of other features
902005 GIS User Group Meeting GPS Background Maps
- Depending on the GPS model and background map
detail, display of background maps in a GPS may
be painful to view at small scales - Can set to display at specified zoom levels so
the most general background layers will display
at small scales and more detailed background
layers will display as the user zooms in to the
map page - Can modify when point and polygon background maps
start displaying at certain zoom scales within
the Garmins Map Setup options
912005 GIS User Group Meeting GPS Background Maps
- Requirements to load background maps
- Sendmap.exe loaded on computer c\gpssendmap\sendm
ap.exe (Setup file located V\drs\apps\gps\gpssend
mapsetup.exe) - Background maps with .img file extension stored
in a folder location without spaces (i.e.
C\GarminMaps) - The standard Garmin download cable with a COM
Port connection. A USB version of sendmap exists
but it has not been fully tested yet . . .
922005 GIS User Group Meeting GPS Background Maps
- Options when loading Background Maps
- Doesnt seem to be a limit to the number of .img
files that can be loaded (other than the overall
map memory space) For instance, the Garmin Map 76
has 8 MB map space - Existing background maps including MapSource
maps will be erased from GPS map memory when
loading new maps (does not include the basemap
that is included in all Garmin Map units)
932005 GIS User Group Meeting GPS Background Maps
- There are different menus and terminology used
among the Garmin Map units to set up Background
maps, but options include - Display only the background maps that you select
- Adjust the map detail (adjusts the scale at which
each zoom level will start displaying) - Display point and polygon labels
- Display point and polygon features depending on
Zoom Level
