Mapinfo google maps maps in mapinfo free11/2/2023 If you’ve found spatial data and are looking to filter out the unwanted data, I’m going to assume you know a little bit about mapping. Sounds like it’s going to be complicated, I know, but I’ll make this painless. “Features? Expressions? Queries?!! I just want to map my sales data!” In a GIS this is done by selecting our desired features using an expression or query, and deleting the rest. The task here is to remove all of the features from the dataset that you don’t need. Short of making a strange map with lots of plain colored areas and then some nice shaded Texan counties, what can we do to trim the fat, so to speak, and filter out all the information we don’t need while keeping all the good data we do need? If you’ve ever downloaded a shapefile from the US Census Bureau’s website, you’ll find this is a common problem. Problem is, like most map data sourced from third parties, this Shapefile contains features and information outside of your area of interest - in fact, it contains geometry and attributes for every single US county. Now, you’re ready to make a web map of sales data for Texas or add the data to your online GIS. So you’ve sourced the perfect shapefile covering US Counties with demographic and population data, and some neat geographic information like the square mile area of land and water for each county.
