DISHAA is a free Android app created by Soorya Online that is perfect for modern surveying and mapping. This bilingual app (in Hindi and English) contains many useful tools that can be used in modern surveying and mapping.

One of the tools is the compass that shows the 16 directions in Hindi and English, which helps a lot in survey and mapping work. Another useful module gives the technical location details of any ground control point in Hindi and English. This module provides details of latitude, longitude, altitude, bearing, speed, etc. If surveyors use the data provided by Dishaa instead of dummy coordinates and altitude, the accuracy level of the survey will increase manifold.

Dishaa also contains a unit converter that converts between many units related to temperature, weight, length, power, velocity, area, volume, etc. The unit converter is bilingual, available in Hindi and English. Another module in this app is a web module that can be used to send queries related to surveying and mapping to the server where experts in the field will answer your queries. It also contains many user manuals related to machines used in surveying and mapping, as well as a video tutorial section that can be used to learn ETS survey.
