Submitting data to Oregon WeedMapper
WeedMapper Request for Data
The WeedMapper project accepts noxious weed distribution data from cooperators on a yearly basis to update maps. This usually occurs through the late fall and winter seasons and notification is posted on web sites and through list serves.
What type of data are we looking for?
Any location information that has been collected for Oregon state-listed noxious weeds. This includes updates from the field season for those who have already contributed data, and all past and current data from new contributors.
The following information is required:
* Exact weed location (lat/long or UTM coordinate) or GIS shapefile
* Type of datum used to collect location (there is a setting on GPS units)
* Weed species name (common and scientific)
* Contact person name, organization, address, phone and email address.
* If providing an update, please indicate if the data replaces earlier information supplied or if it is in addition to it.
The following information is also requested:
* Number of plants (in quantity or net and gross acres)
* Type of location (roadside, pasture, rangeland, forest, field, urban or riparian)
* Frequency (spot, patch or solid stand)
* Treatment (manual, mechanical, chemical or none)
* Land ownership type (USFS, BLM, state, county, city, private, unknown, other)
* Date of find
What format do we want the data in?
Data needs to be in some type of electronic format. Small sets of data can be entered directly into the weed sighting report form at www.weedmapper.org. For larger data sets the following format is preferred:
GIS Shapefile – one per weed species. These can be point, line or area files, but point files are preferred. Please include a note about what datum was used to collect the data (e.g. WGS 84, NAD 27, etc.) and what projection the shapefile is (e.g. Oregon Lambert, state/plane, etc.) if a projection file is not part of the shapefile.
Other electronic formats are also acceptable:
* Shapefiles with more than one weed species
* Arc coverages
* Spreadsheets
* Any other format that has the data stored electronically in table form.
When do we need the data?
A deadline date to send in your information will be announced yearly and must be met by cooperators to have data included in the current year’s update. Information in the preferred format will be given priority.
Who should you contact?
Alex Park, Noxious Weed Technician, Geographic Information Systems (GIS) support and data map development. Please contact Alex if you have data to share and he can arrange the best way to receive it from you.
Thank you for your support of WeedMapper.
