logo Calflora Observation Download Help
 

The Observation Download Application provides a way to download a set of plant observations from the the Calflora / BAEDN online database in a form that is readily assimilable by another database or spreadsheet.

Searching and Dowloading

    Enter some selection criteria (for instance, County = "Marin" and Plant Status = "non-native"), and press the Search button. The first 750 records that match the criteria will appear in a table at the bottom of the page. If more than 750 records match, only the first 750 will be displayed, and to see all matching records, you will need to download the result set. To download, choose an Output Format other than "Table" (for instance, "CSV" to go into Excel, or "Tab delimited"), and press the Download File button.

    To see the results in Google Earth, do a search, choose "KML" as the value of Output Format, and press the Download File button.

    Lines and Polygons: Most records include a point location. Some records also have an associated line or polygon.
     

      To search for records that only have a point, and not a line or a polygon, set Geometry to point.

      To search for records that have a line, set Geometry to line.

      To search for records that have a polygon, set Geometry to polygon.

      To search for all records, set Geometry to any.

      To download matching records as a point shapefile, set Output Format to Shapefile: point. To download matching records as a polygon shapefile, set Output Format to Shapefile: polygon, and similarly to get a line shapefile.

      It is possible to download a GeoJSON file containg a mix of feature types; in other words, points lines and polygons. To get records including any available geometries in the form of GeoJSON, set Geometry to any and Output Format to GeoJSON. However, GIS products like Quantum GIS do not really accept GeoJSON files containing heterogenus feature types; QGIS will look at the first record, and if it is a point, it will only load the point records in the rest of the file.

      Geometry is not included in the various flat file formats (CSV).

    If you are looking for a specific plant, note that the Scientific Name and Common Name fields are typeahead enabled -- type in part of the name, and then choose the exact name from a drop down list. If you choose a full scientific name, the search will also look for synonyms of that name. If you choose just a genus name, the search will not look for synonyms, but instead look for all scientific names that begin with that genus.

    There is a maximum of 150K records per download. If you need more than this, try chopping the state up into regions by latitude.

Views

    You can download the data through various views (column sets). Use the Column Set selector above the results table to choose a predefined view, and/or use customize to modify a predefined view.

    Current predefined views include:

    Basic Data
    Only core data fields.

    Weed Data
    Core fields plus weed specific fields.

    Weed Data Export
    A short list of fields including Management Status.

 

Hints for Using the Application

  • Generating a shapefile on the server requires a lot of server resources. If you set Output Format to Shapefile: ..., and the results include a large number of records, the download may fail. If this happens, choose a different Output Format, and convert the results to a shapefile on your own computer after the download. If you need to download polygons or lines, try downloading as GeoJSON, and use Quantum GIS to do the conversion.

  • If the results you are getting are too dense (too many points), you can impose a grid on the results to thin them out. If you set Grid Cell Size to "30 arc seconds", the results will contain at most one record per grid cell, where the side of a grid cell is 1/120 of a degree.

  • It is no longer possible to get unpublished records from this application. This change was necessary for security reasons. Please contact support if you need to download unpublished records.

Fields in Alphabetical Order

Comments
Anything of interest about the plant or site.
 


Common Name
The common name of the plant observed.
 


County
Full County name e.g. Riverside.
 


Distribution Code
The distribution of the plant across the landscape.
CodeValue

Distribution
Use this field if the input contains words like single, individual, one, scattered, monoculture, or patch.
 


geometry
If there is a shape (line or polygon) associated with a record, the value of this field will be the ID# of the shape. If there is just a point location acssociated with a record (no shape), the value of this field will be 'P' (point).

To download the entire record including the shape in the form of GeoJSON, set the Output Format to "GeoJSON" and include the geometry field in the output Column Set.


Gross Area Count
Gross Area: The area of ground covered by the patch, if you drew an imaginary line around the outer boundary of the infestation.

The number of units e.g. 15.

GrossArea
Use this field if the gross area count and units are both present in a single input field e.g. 15 square meters.
 


Habitat
The primary habitat type where the plant is growing.

  • Forest: Tree-dominated, generally with a closed canopy (e.g., redwood forest, eucalyptus grove)
  • Open Woodland: Tree-dominated, but with open areas between the trees (e.g., oak woodland)
  • Scrub/Shrubland: Shrub-dominated, with few or no trees (e.g., coastal scrub, chaparral)
  • Grassland / Open Field: Grass-dominated, with few to no shrubs or trees
  • Stream bank / bed: The banks or dried bed of a stream, creek or river
  • Wetland: Herbaceous-plant-dominated, with standing water at least part of the year and wetland indicator plants (e.g., cattails, rushes, pickleweed marsh, vernal pool)
  • Open Water: Pond, lake, river, estuary, etc.
  • Beach / Dune: Generally some open sand, or there would be if not infested with iceplant or European beachgrass
  • Planted (Lawn, crop, etc.): An area purposely planted for agricultural, recreational or ornamental use.

ID
