Working with large datasets

While Podaris supports a range of formats and large urban-scale GIS datasets, it is not an application for storing "big-data". Importing datasets which are extremely large will cause project performance to degrade or fail to import entirely.

Podaris sets a limit on both the total size of uploaded datasets and a maximum number of coordinates per feature for the datasets that you import into Plan.

Due to the limit on the number of coordinates per feature, you may experience an error stating that "coordinates must contain less than or equal to 50000 items", even if your imported dataset is a small file. This is commonly caused by large high-resolution polygons used to demarcate regional boundaries.

We suggest using a GIS application to simplify complex or large datasets before importing them. This will also have the effect of improving the graphical rendering performance of your projects within Podaris.

Simplify Geometry

You may wish to simplify complex geometry using GIS tools. Here are some third-party tutorials for popular GIS applications:

Simplifying polygons in ArcGIS.

Simplying polygons in QGIS and R.

Simplifying lines in ArcGIS.

Aggregate Points

If you are trying to import a large number of points, you may consider aggregating those points into polygons.

Aggregate points to polygons in ArcGIS.

Other Solutions

If you are still having difficulty working with datasets comprising a large number of points, lines or polygons, you may wish to link to an externally hosted GIS server instead of uploading your file directly to Podaris.
