There are a number of GIS solutions available, and about a 100 of them are from Indian companies. Unlike a lot of them, JT Maps, a solution named after the parent company, provides a host of features at a very low price. Its biggest incentive- its free trial has all the features of the retail version. Except for a watermark in its printouts, it has no other limitations or reminders. JT Maps 2005 supports 23 different image formats that include outputs from a few satellites like IRS-1C and Landsat-7. The software is very technical and this makes it slightly bewildering. JT Maps is a suite of two applications and four utilities. Other than the main JT Maps program, there is the JT Spectral application that takes in the image file and performs analysis on it. It also allows you to classify and add layers to the image according to what ISO or mean data is represented by it. The utilities are for translating between files, deriving projection transformation based on elevation data and converting between different mensuration units. The Vector Re-georeferencing tool lets the user map objects on a map to their geographical coordinates. The architecture of the suite allows students, insurers, underwriters, disaster planners, the government, military or anyone who needs to use a GIS system to use it.

JT Maps allows the user to add different user-created layers (the yellow areas) to an image 

Bottom Line: A comprehensive GIS application that can be used by a variety of entities for different needs. At its price, it is a real steal.
