DNRGPS released – replaces DNRGarmin

Posted on by

The Minnesota DNR released DNRGPS on February 15, 2012 and has already issued an update to fix some functionality problems. DNRGPS is the long-awaited replacement for DNRGarmin 5, and is designed to address incompatibilities between ArcGIS 10 and DNRG. It will also work with GPS units not manufactured by Garmin, Inc, prompting the name change.

DNRGPS is written as an Open Source application, and utilizes other open source software for portions of its core functionality (notably gpsbabel and GDAL). The developers are still working on updates to the program – be sure to read the known issues, release notes, and help file found on the application’s web page.

DNRGPS requires Windows XP or Windows 7, and works with ArcGIS 10 and Google Earth. Long-time users of DNRGarmin will want to do some testing before using DNRGPS on a daily basis. The move to open source underpinnings has changed how the software operates, notably how projections are handled. The ArcGIS toolbar is no more, but Geodatabase functionality has been added.

Stay tuned for more impressions and tutorial data.

ArcGIS Geoprocessing tools

Posted on by

Long-time users of ESRI products may remember the “Geoprocessing Wizard” tool that was available in ArcView 3.x and in ArcGIS 8. Though it was handy to have these common analysis tools in one location, this wizard was removed in ArcGIS 9 and the associated tools were ‘relocated’ to other toolboxes.

The functions of the Geoprocessing Wizard included: Merge, Clip, Intersect, Union, and Buffer

These tools may be found in the following toolboxes (both in ArcGIS 9 and 10):

Merge: Data Management Tools > General > Merge
*the Merge tool was called ‘Append’ in ArcGIS 9.0 and renamed in version 9.1 and later
Clip: Analysis Tools > Extract > Clip
Intersect: Analysis Tools > Overlay > Intersect
Union: Analysis Tools > Overlay > Union
Buffer: Analysis Tools > Proximity > Buffer (or Multiple Ring Buffer)
