Vitis Gap Analysis and Specicies Distribution Models

Vitis Home Page > All information presented on this site is in draft format and will be updated.

2025 09 25 update

  • improved FNA filter to capture locations where state/county was not define in attributed data for points

  • resolved model runs for all species

    • largest area species required 6 rather than 10 model iterations due to memory allocation issues with 1km models

  • added northern and southern lat lon filter to account for european or poor lat lon values in data

  • update the run summary to render the 1km results, all maps resampled to 5km resolution

2025 08 19 update

  • added additional data on mexican species

  • improved capture of data on Vitis x species

  • Expanded lat lon filters to include both north and south america

  • remove most datasets that utilities the 2018 data pulls

  • new model and conservation assessments

  • updated taxonomy and synonym listing

  • species with no

2025 08 01 update 2

  • New input data from Genesys, GBIF, direct communication with J Wen.

  • Models generated with 1km biogeographic variables

  • maps on summary html are resampling to 5km for display purposes. We can provide original resoluation data, just cant display it do to file size limitations of the leaflet maps used to display spatial data in the htmls.

species with no lat lon do no have generate html summaries at this point - Vitis rufotomentosa - Vitis x champinii - Vitis x doaniana

The following model run include the details from the 11-05 update plus an adapted spatial filting process.

Spatial filter was performed by the spthin package.

    1. All Germplasm records we kept for the modeling process as these represent the high confidence observations
    1. All herbarium records where spatial thinned to a distance of 5km.

We getting very close to finalizing results for the project. The following examples showcase the difference in results after applying the following data filters.

  1. A state level filter is applied based on Flora of North America desiginated habitat. Any points outside of this area are excluded. This filter only applies to the United States. All data from Mexico and Canada is included.
  2. Any occurrence data that was flag by the county review as “Exclude” or “Questionable” was removed from the analysis.
