Clickable map showing JPEG scans of the 1:100,000 scale geology series for entire country of Peru. These JPEG files are barely legible, but they are useful because they are one complete scan and they can easily be georeferenced in to a GIS. If you own the paper copy of a given map (for reading the fine print) then combined with these JPEGs you can georeference and digitize cartographic and geologic features from throughout the country.

Despite the blocker, Firefox allows you to save out the JPG files.

Note: the grid system in these maps is PSAD 1956 (La Canoa) not WGS84. See this post concerning georeferencing and reprojecting of these scanned maps.

Teaches a number of steps for incorporating geological field data into an Arcmap project . The class includes georeferencing scanned maps (USGS Topos) and how to digitize vector shapefiles from the features depicted on the scanned map.

Demonstrates how to create user-sortable tables in an HTML page using a simple Javascript tag. Good way to distribute static tabular data on web pages.

Browsable text-based website providing population and coordinates for all cities and large towns worldwide. GoogleEarth positions also available.

Large and active forum discussing ArcGIS issues. Great place to search for answers to puzzling ArcGIS problems.

To convert DMS values to decimal degrees (e.g., 45:30:30 to 45.50833), multiply the DD:MM:SS value by 24, and format the cell as General. For example, =A1*24

Simple form from NOAA for calculating the most current magnetic declination for any location on the planet. For use with declinating compasses.

Wikipedia contains a fairly detailed description of the functioning of the GPS system.

Useful list of suggestions from the USFS about use of research grade vs recreational GPS units, getting reception under the forest canopy, projection transformations in Arcpad 7 and more

Useful tutorials introducing techniques in ArcGIS

Allows you to send very large files to people via email. Rather than using attachments the recipient just gets a link that they click on. This service is better than YouSendIt.

This unit conversions page is useful because it also supports areal and volumetric conversions.

On a related note, unit conversions are possible inside of Arcmap as follows. "When editing in ArcMap, you can do on-the-fly unit conversion if you specify the unit type when you type a distance (by right-clicking). When you enter a distance into a pop-up window, press F1 to get a list of the unit abbreviations you can use." (Arcmap help)

Automatically retrieves data for your current Arcmap work frame from the following online sources
