Dear Jaime, 1. You want to make Population density map. The map making process depends on your input data.
a. If you have population census data by polygon, the process is straight. Start rasterizing it. Do histogram calculation and create new column of population density (in histogram table) by dividing population data by assigning it to the raster map. You can apply CLFY function to further classify among your classes. Or You can do it on Table Calculation as well. b. If you have point data and these data have population value (but not density), you can interpolate the point, classify among some classes and make some areas. Then redo the step a.

Someone said me that it's possible creating a counting filter or something else. Do you know how I could it? Thanks for your help, Sincerely, Jaime ************************************************************************ ************************************** Jaime Bonachea Pico Departamento de Ciencias de la Tierra y Fisica de la Materia Condensada CITIMAC (Facultad de Ciencias) Av.
