Prospectivity maps (Geoscience data)

SamanTavakoli — Mon, 09 Nov 2015 15:51:15 GMT

Hi,

I am a geophysicist and I am going to create a prospectivity map.

In other words, I've got several geophysical maps (e.g. magnetic anomaly, Bouguer anomaly etc.) and I would like to pick up the values for some interesting areas (e.g. magnetic anomaly weight 2/5, Bouguer anomaly weight 4/5....), assign weight to them and tell the program to find other areas in the map with similar values. Does any one know how may I do this?

Best regards,

/Saman

Take a look at ArcGIS Help 10.1- Hotspot Analysis

Let me know what you think.

Dear Mitch,

Many thanks for your answer. What I am still missing is the way to do it. For someone who has not been working with GIS processing tools for many years, applying the hot spot would be impossible unless a very clear step by step guidance is provided.

Is there any link or description for a beginner about how to do it?
