The current version of DNRGarmin (5.4.1) is not entirely compatible with ArcGIS 10. That is, the toolbar will show up in ArcMap 10 and it will launch the DNRGarmin application but DNRGarmin does not recognize that ArcMap is open. We have not yet begun programming the new version.
The work around for the time being is:
File->Save To->File and File->Load From->File. You can save to a shapfile and add it manually to ArcGIS 10, as well as load from shapefiles created/modified in ArcGIS 10.
AddXY (v1.0) is an ArcView extension that should work with ArcView 3.0 and later. It adds the X and Y values of points (shapefiles or coverages) to their attribute tables. It adds the X and Y values of polygon centroids (shapefiles or coverages) to their attribute tables. It will add the X and Y value of a polygon’s labelpoint to its attribute table. Due to a bug in ArcView, it does not work consistently with node coverages, so this has been removed. The X and Y columns in the attribute table should be created with the same names and precision that the ARC/INFO command “addxy” would create.
This Arcview extension provides a dialog-based tool to simplify the currently selected shapes in a polyline or polygon shapefile. This tool is used to generalize, or weed out, vertices that do not add to the desired level of detail in the geometry. A tolerance is specified to check whether or not vertices should be retained.
This script is a simple implementation of the Douglas – Peucker algorithm used in ARC/INFO and PC ARC/INFO. The dialog is initiated from a button in a View GUI.
The extension does not make a new shapefile. It changes the currently active polyline or polygon shapefile. Changes can be Undone using the standard shape editing tools in Arcview.
The extension will reduce the quality of the data. Any metadata for the themes should state that the data are modified.
The extension will generalize all the selected polylines or polygons.
Results are very dependent on the polyline or polygon geometry. While the shape endpoints are maintained, interior points may be eliminated. Other shapes in a network that may begin or end at an interior vertex may now be dangling. A complex shape may cross itself after being generalized. Neighboring polygons will no longer match edges. Proceed with caution.
This script does not recalculate lengths or areas. They may have changed as the shapes are simplified. The View.CalculateFeatureGeometry (calcapl.ave) sample script can be used to update the values.
This extension was built to provide users the ability to directly transfer data between Garmin GPS handheld receivers and various GIS software packages. Using this program a user can use point features (graphics or shapefile) and upload them to the GPS as Waypoints. Line and Polygon Graphics or shapes can be uploaded to the GPS as Track Logs or Routes. Conversely, Waypoints, Track Logs, and Routes collected using the GPS can be transferred directly to ArcView/ArcMap/Google Earth/Landview and saved as Graphics or Shapefiles.
This program has a real-time tracking mode that allows users to follow their progress on the ground within an ArcView View Document, ArcMap Data Frame, or Landview Map. This real-time track log can be saved as either points or lines as a set of graphics or in a shapefile.
At this time DNRGarmin contains (but is not limited to) the following functionality:
Download Waypoints/Tracks/Routes – Download waypoints, tracks, and routes from Garmin GPS and save as ArcView Shapefiles or Graphics
Upload Waypoints/Tracks/Routes – Upload waypoints, tracks, and routes to Garmin GPS
Real-Time Tracking – Collect real-time locational information and store as graphics or shapefile
Waypoint to Point – Converts Waypoints downloaded from the GPS unit into a point shapefile or graphics
Track to Point/Line/Polygon – Converts a Garmin Track log to an ArcView graphic or shapefile
Point to Waypoint – Convert Point shapes or graphics to a GPS Waypoint
Line/Polygon to Track – Converts a line or polygon to a Garmin Track
Point to Line/Polygon – Converts Point themes to Lines or Polygons
Add Documentation to Features – Adds basic documentation to ArcView themes including Name, GPS Model, Date, Agency, etc. – ArcView 3.x only

Hawth’s Analysis Tools is an extension for ESRI’s ArcGIS (specifically ArcMap). It is designed to perform spatial analysis and functions that cannot be conveniently accomplished with out-of-the-box ArcGIS.
Most of these analysis tools have been written within the context of the ecological applications I am involved in (movement analysis, resource selection, predator prey interactions and trophic cascades). However, they have been created in such a way as to be as broadly applicable as possible such that I hope people from many disciplines will find use in this set of tools.
There are three types of tools in this kit. First, there are simple tools that automate mundane tasks (e.g. deleting many fields at once from a table). These will likely be useful to anyone.
Second, there are tools that are designed to be part of an analysis workflow. For instance, random point (or stratified random point) generation, minimum convex polygon delineation, summarizing raster layers in various ways, etc. These too are likely to be useful to many people.
Finally, there are tools that target specific, ecology related analyses (for instance, various movement model applications). These will likely only be of interest to ecologists.
Specific detail of the tools can be found on the Tools page.
Hawth’s Tools is FREE. You are free to distribute it and install it anywhere you choose. As there are continual updates and additions to the tools, it is recommended that you check this website from time to time for more recent versions.
HydroSHEDS (Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales) provides hydrographic information in a consistent and comprehensive format for regional and global-scale applications. HydroSHEDS offers a suite of geo-referenced data sets (vector and raster), including stream networks, watershed boundaries, drainage directions, and ancillary data layers such as flow accumulations, distances, and river topology information.
HydroSHEDS is derived from elevation data of the Shuttle Radar Topography Mission (SRTM) at 3 arc-second resolution. The original SRTM data have been hydrologically conditioned using a sequence of automated procedures. Existing methods of data improvement and newly developed algorithms have been applied, including void-filling, filtering, stream burning, and upscaling techniques. Manual corrections were made where necessary. Preliminary quality assessments indicate that the accuracy of HydroSHEDS significantly exceeds that of existing global watershed and river maps.
The goal of developing HydroSHEDS was to generate key data layers to support regional and global watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution and extent that had previously been unachievable. Available resolutions range from 3 arc-second (approx. 90 meters at the equator) to 5 minute (approx. 10 km at the equator) with seamless near-global extent.
HydroSHEDS has been developed by the Conservation Science Program of World Wildlife Fund (WWF), in partnership with the U.S. Geological Survey (USGS), the International Centre for Tropical Agriculture (CIAT), The Nature Conservancy (TNC), and the Center for Environmental Systems Research (CESR) of the University of Kassel, Germany. Major funding for this project was provided to WWF by JohnsonDiversey, Inc.
