We’re going to go further with our calculations and visualization than that tutorial. If you don’t have them in the same download, here is the basic process to join the data table to the polygons: Since they’re different layers (one is polygon and one is point), we’ll have to merge them later. Great for us – both the parcels and the data are in the same download. This is the new format for City GIS appraisal data products. NOTE: property attributes are assigned to points, not polys. Contains parcel polygons (ParcelID) and appraisal points data (ParcelID to join to polys) for certified roll year 2016. Tax Appraisal Data 2016 – Points and Polygon. Interestingly, the Dallas tax appraisal data (from the county) has this description: If you don’t find it, ask your city if it’s available. Depending on the size of your city, it might not be available online or might not even be available in digital form. To find the city you want, google “ GIS”. Dallas the city is mostly within Dallas the county so we’ll stick to that part for this. Fortunately, Dallas is a big enough city to keep its city parcel data on its city website. The Dallas County tax data is at the Dallas County Appraisal District website. In Texas, the tax assessments are done at the county level, so you may have to look in multiple locations to find the data you want. I also have only worked briefly with QGIS as most of my training was with ArcMap. I’m going to visualize Dallas here because I haven’t done it before, but I have worked with the data.
#VISUALIZE VALUE HOW TO#
I’m going to show how to do that here using free tools. One of the easiest ways to get a big picture view of your city’s financial situation is to do a quick value per acre visualization. Chuck Marone of Strong Towns always says if you lose money on each transaction, you don’t make up for it on volume. One of the more important factors affecting long-term community resiliency is whether the city can afford to provide the services residents expect.
