![]() ![]() If your data uses another projection or different units, you can use My World to un-project and convert it to the proper units by selecting Un-Project Shapefile… from the File menu, or by clicking the Import Data From File… button in Construct mode. “My World accepts shape data only in Unprojected Latitude and Longitude in Decimal Degrees, and the longitude must be in the range -180 to +180 (rather than 0 to 360). But once I got past the hassle involved with importing my own data, I had a lot of fun with this program. That this wasn’t totally straight-forward was my only real disappointment with My World. ![]() I did find adding my own shape files a bit confusing at first since My World doesn’t support the shape files in their native projection and requires them to be un-projected. * ESRI Shapefile, Comma-Separated Values, Tab-Separated Values, and GPX Waypoint Files plus a variety of Grid and Image file types, and WMS data feeds ( more info here). My World supports the following types of data files and/or folders for reading and writing shape data: There is a fully functional 45-day trial period available. It is marketed to educators, but licensing is also available for non-educational use (for research or other non-educational uses) directly from Northwestern University (currently priced at $99 US per single license). It provides a robust subset of capabilities from a professional GIS environment, including multiple projections, table and map view, hyperlinks, and a common language approach to conducting analyses. Built in Java, My World runs on Macintosh OSX and Windows environments. My World is distributed by Pasco Scientific ( ). Northwestern University has developed a GIS called My World, which engages ESRI’s MapObjects Java technology. This brings me to a review of My World GIS (v4.1.1) for the Mac (it can also run on a PC). My conclusion with these existing programs is that those that are easy enough to plug-and-play lack basic analysis capabilities, and those that show promise for being very powerful are limited by not being plug-and-play. ![]() Also, QGIS with Grass support looks very promising (if I can figure out how to implement it). ![]() Also, let me admit I am not sophisticated enough of a Mac user yet to do everything required to run OpenOX-Grass (it requires Apple X11) but I will try to work toward this because it does look very powerful and the price (~$60 US) is right. Viewing the data is great, but I definitely need more. The biggest disappointment is none of the really easy ones have any ANALYSIS capability - I personally don’t think it is a GIS if you can’t analyze the data. The tools I’ve downloaded so far are Quantum GIS (QGIS), UDig, SimpleDEMViewer, and OpenOX-Grass. I have been searching for an easy, inexpensive GIS system to use on my Mac and have been continually disappointed – until now.įirst, let me give a quick overview of what I have found… (a more comprehensive review of these systems is on ). I continue to use my PC only for GIS needs and every time I use it I hate to boot up the system at all. While I knew there was a dearth of GIS software for the Mac, I knew all the other reasons for a switch made good sense for me. (2007) Earlier this summer I made the switch to a MacBook Pro OS-X. UPDATE: My World GIS is no longer being developed and may not work with the latest operating systems. ![]()
