How Data Affects Map Render Performance

No two data sets are the same, and each has a different impact on map rendering performance. While larger data sets can take more time to render, there are other aspects of data that also affect:

  • The number of records in a table that is visible and within the map view.
  • The complexity of the map features (a simple building outline with four nodes renders more quickly than a river flood boundary with 100,000 nodes).
  • The projection of the data (data that needs to be re-projected to align with base mapping takes longer to render).
