Data Loader and Thematic Mapper give you a quick and easy way to import and thematically map outside data sets in LandVision™.

Data Loader lets you load shape and .csv files in a few simple steps so you can work with all your location-based data in one application, regardless of its source.

Loading Address Data
  • Preparing your Address and Coordinate data for importing
    • DMP’s Data Loader requires address and coordinate data to be stored in a Commas Delimited (*.csv) file.
      • To save a database or spreadsheet file as a Comma Delimited file, simply perform a “Save As” and select “CSV (Comma Delimited) (*.csv)” for “Save as type.”
    • DMP’s Data Loader requires certain fields to be included in your Address and Coordinate *.csv files. Your *.csv file must contain the exact fields below:
      • Required Address fields: source_address, source_city, source_state, source_zipcode
      • Required Coordinate fields: latitude, longitude
    • DMP’s Data Loader cannot recognize *.csv field names that contain spaces or special characters.
    • DMP’s Data Loader has reserved field names which your *.csv file cannot include: Key.
    • DMP’s Data Loader has an upload file size limit of 30MB.
    • DMP’s Data Loader lets you append data sets. To do this, you need to have a field that’s a unique identifier for each record.

  • Loading an Address Data Set
    • Click on “Address Loader” from the Load Data heading. The “Load Address Data” dialog box will appear.
    • Click on the “Browse” button to the right of the “File Name” input box to select your *.csv file containing your address data set.
    • Select the layer you created for this address data set from the “Layer Name” pick list.
    • Enter your email address to receive confirmation that your coordinate *.csv file has been successfully loaded and is ready for display in LandVision™.
    • Click the “Load” button.
    • A confirmation box will appear notifying you that your data load was successful.
    • Once your address file is ready for display in LandVision™, you will receive an email at the email address you provided in the prior step. Note: your confirmation email may be delivered to your junk folder



  • Appending Data to an Existing Address Layer
    • If you would like to add or modify address data you’ve already loaded, you can do so using the “Foreign Key” field.
    • Make sure your *.csv file contains a field that is a unique identifier for each record (i.e. it contains a value for each record that is unique, and not repeated in the data set). This field needs to be in your both your original *.csv file and your updated *.csv filed and must be mapped during the Create Layer step.
    • When you are ready to append data to an existing layer, do not create a new layer and follow the steps above for loading address data. Make sure to pick your original layer from the Layer Name pick list.
    • Select your unique identifier (aka Foreign Key) from the Foreign Key pick list.
    • Click the “Load” button.

Loading Shapefile Data
  • Preparing a shapefile for importing
    • DMP’s Data Loader requires shapefiles to be in a zip file format. When adding your shapefile to a zip file, the following files are required: *.shp, *.dbf, *.shx.
    • DMP’s Data Loader has an upload file size limit of 30MB.
    • DMP’s Data Loader requires shapefiles to be in unprojected format.
      • If you are importing a shapefile you’ve extracted from your own GIS system, you have the option to extract it as unprojected.
      • If you are importing a shapefile you’ve received from another source, you need to verify it is in unprojected format. If it is projected, you need to use a GIS tool to reproject the shapefile to GCS NAD 1983.
      • A free application available for reprojecting shapefiles is “Map Window GIS.” You can download Map Window GIS here

  • Loading a shapefile
    • Click on “Shape Loader” from the Load Data heading. The “Load Shapefile Data” dialog box will appear.
    • Click on the “Browse” button to the right of the “Zip File Name” input box to select your zip file containing your shapefile.
    • Enter a name for your layer. This is the name that will be displayed for your layer in the LandVision™. Note: layer name does not support special characters. Upper and lower case letters, spaces, and underscores are all supported.
    • Enter your email address to receive confirmation that your shapefile has been successfully loaded and is ready for display in LandVision™.
    • Click the “Load” button.
    • A confirmation box will appear notifying you that your data load was successful.
    • Once your shapefile is ready for display in LandVision™, you will receive an email at the email address you provided in the prior step. Note: your confirmation email may be delivered to your junk folder
