Hi all, I have a request to create some maps showing HF coverage reliability based on time of day, sun strength and other factors that may affect HF propagation. I have output that I can use to a point file and map the x/y's. The point file is created by a program called, ICEPAC. ICEPAC was developed by the US Gov't to aid in RF propagation. It is able to let the user create a reliability matrix based on time of day, sun position and etc. The matrix can be 32 x 32 or greater and can be controlled by the user. The total distance of the 32 x 32 plot from left to right is approx. 10,000 km. So, I guess if you know how many rows across, 32, then you can take 10,000 km and divide it by 32 to get 312.5 km in size for each grid cell? The output, created by ICEPAC, is a map that shows thr reliability of HF depending on your parameters. The program gives you a export image option and an export data option. The export data option creates an excel file of data with 1024 rows and are attacehd by a lat/long. My problem is this, can I use ArcINFO to create a grid of the matrix from ICEPIC and then create contours that show reliability? How do I get the points.dbf to the correct format to create a GRID?
