how to differ the urban with suburban (rural) areas in classification using arcGIS

[w1malik]

Is there any way to spatially recognize the densely populated area with sparsely populated area so that i could see the change with urban and sub urban areas in my area of study and further i want to see the temperature change between both of the areas?

please guide me accordingly.

you first need a band combination that accentuate the appearance of urban, from there you can use supervised classification to detect urban and rural area

 

for temperature change, I think using thermal data will suffice, based on the classification you did before, you can overlay on thermal data, and generate thermal classification based on the urban or rural area

 

for this job, I recommend you using remote sensing software like ENVI or ERDAS, its easier than ArcGIS

THANKS FOR YOUR RESPONSE REGARDING MY QUERY.

WOULD U PLEASE EXPLAIN ABOUT OVERLAY ANALYSIS. HOW CAN I GENERATE THERMAL CLASSIFICATION BASED ON URBAN OR RURAL AREA. THANKS FOR YOUR SUGGESTION FOR USING ERDAS IMAGINE. I HAVE IT AND USING. AFTER RETRIEVING THE TEMPERATURE DATA OF LANDSAT 5 I HAVE PROBLEM TO MOSAIC 2 TILES OF CONSISTING MY GEOGRAPHIC AREA. WHEN I MOSAIC THE TWO TILES, THE BLACK BOUNDING BOX COVERING THE RECTANGLE AREA OVERLAY THE SECOND TILE WITH BLACK AREA ON IT. HOW CAN I GET RID OF THAT BLACK AREA OVER IT?
