I am making a micorwave communication analysis tool based on Web development for my dissertation. So i realised i needed to understand the geo data which is available in the form of SRTM digital elevation data, using which elevation data of a particular portion of earth.

For this i have a transmitter and receiver position set by the user and now i am trying to map the elevation data from the srtm data with the tranmitter and receiver, which will be used to find if the freznal zone is clear or not.

I have no knowledge on GIS tool. I googled and found out about splat tool which essentially runs on linux and i have a windows platform, so not going ahead with it atm also i learnt about google elevation services but couldnt find anything relevant.

Essentially iam trying to figure out how i can map by data to a drawing with transmitter on left and receiver on right with the elevation data shown in some sort of a picture.

I know what i am asking is very vague but i cant figure out how to do it. I need directions that can help me out as i seem to have no idea where to even begin reading about this. Any help will be highly appreciated.

Ok so after reading a lot here I will write what I did.

The simplest thing anyone can do is to use Google's elevation service and you never would require to know what is srtm data as all the work is done by Google in the background.

But before concluding to this answer I downloaded NASAs SRTM data for all of the word and figured that the data for 90 m resolution of 1degree lat and 1 degree longitude is stored as signed integers in 2 bytes. I was able to read the data using java but realised for using JavaScript for my web site and making the local file available for the manipulation isn't going to work (I haven't setup a server yet to do this task) so I realised Google's Apis's are better deal for this.

Now I am hunting for landcover api's. If someone has any idea of api's available in this regard would be of great help
