Vegplot Text Note(s): A scan of the original data (i.e. field sheet(s), edits, manuscripts, notes, and other associated data) is available in the RO10 Field Documentation Archive maintained by Adolfo Diaz, RO10 GIS Specialist. This web map can be accessed using the following link: http://arcg.is/1iDqnO Google Chrome is recomended to explore the map. At its full extent, the web map will display the 9 states that make up Region 10 along with a summary of the number of pedons per state. Since there are too many points to display at the full extent you will have to zoom in to an approximate scale of an average county. Once zoomed in you will notice that the pedons will appear both in the legend (Table of content area) and in the map. Once displayed, you can click on any point to open the identification window and get basic information such as: Series Name, location description, Lat-Long and other information. The original document has also been embedded as an attachment and can be previewed by clicking on the pdf file within the identification window. This database represents a snapshot and will be updated once a month. This database can also be directly streamed into an ArcGIS/ArcPro session to be overlaid with your project layers. However, to do so you must have an ArcGIS Online for Organizational account. If you are interested in this please let Adolfo Diaz know and he can work with you to set it up. As a recap, here are the main objectives of this project: 1. Inventory and digitally archive - As soil survey crews finalized surveys and made their way to different offices, many of the original soil survey documentation was left behind or simply discarded as being irrelevant material. The inventory process was an opportunity to collect and organize this legacy documentation. For preservation and accessibility purposes these files were also scanned. 2. Develop a GIS database In order to view the spatial distribution of our inventory and perform spatial queries, pedons with a valid location were digitized. As part of this process, each pedon was assigned a unique siteID using the current NASIS naming convention. 3. Enter into NASIS as needed Having pedons in a GIS gives the user the advantage of spatially assessing field documentation availability and determine whether a pedon should be entered into NASIS for project purposes.
