![]() Granted, even their basic software package contains hundreds of features necessary for sophisticated GIS analysis. ESRI’s “ArcGIS for Desktop Basic” software costs $1,500 for a single user, according to ESRI’s website. The problem with this sophisticated GIS software is that it tends to be rather expensive. The online parcel viewer provided by Dinwiddie County, Virginia (available here) is one of the best implementations of that sort of system that I have seen.īut, for the more computationally intensive tasks, professional GIS analysts use very sophisticated software, such as the software published by ESRI. For example, many localities now make their tax maps available online in web-based GIS applications. Sometimes GIS is useful just to determine where a particular property is located. Not all uses of GIS are quite that computationally intensive, of course. For example, I previously wrote about how GIS is being used proactively to protect the viewshed around Mount Vernon. Uses can range from simply determining the most efficient way to monitor protected properties to analyzing the special characteristics of a property and even the impact of nearby properties on a property. Geographic Information Systems (GIS) analysis is an increasingly important resource for land preservation. But, first, let’s explore why this announcement is relevant to land preservation. #GOOGLE EARTH VERSUS GOOGLE EARTH PRO PRO#Google Earth Pro had previously required an annual subscription fee of several hundred dollars, and I have my doubts as to what the elimination of a paid subscription tier means for the future of Google Earth. Google announced earlier this year that it will now be offering Google Earth Pro for free. ![]()
