Yes Neha, many colleges such as UPES etc include mathematics under the course curriculum of Btech Geoinformatics (GIE). But it is only for the first year (1st and 2nd semester). 2nd year onwards, you will be focusing only on he core subjecs. Also, do no need to worry even if you are not good in mathematics as syllabus of 1st year mathematics is not as much difficult, however you must be clear with the fundamentals.

Hope I answered your query, thankyou!
