My project explores spatial and temporal variations of water quality (dissolved organic carbon sources to be precise) in rivers of the Willamette River Basin. Those ESRI spatial statistical tools are not applicable to my project because 1) points are not representing actual observation points of organisms or diseases for my project but rather representing water quality sampling locations that were selected by me and 2) not only Euclidean distance but also in-stream distances, flow directions, and stream networks affect statistical significance.<\/p>\n<p>I found add-in toolboxes for SSN &amp; STARS and FLoWS that address those two issues mentioned above. These toolboxes were developed by the U.S. Forest Service (USFS). Unfortunately the currently available toolboxes are for ArcGIS 9.3, but the USFS states they are planning to publish new toolboxes for ArcGIS10 later this year.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"http:\/\/webcache.googleusercontent.com\/search?q=cache:5SIzWb38eREJ:blogs.esri.com\/esri\/arcgis\/2013\/01\/29\/ssn-stars-tools-for-spatial-statistical-modeling-on-stream-networks\/+spatial+statistics+arcgis+water&amp;cd=1&amp;hl=en&amp;ct=clnk&amp;gl=us\">http:\/\/webcache.googleusercontent.com\/search?q=cache:5SIzWb38eREJ:blogs.esri.com\/esri\/arcgis\/2013\/01\/29\/ssn-stars-tools-for-spatial-statistical-modeling-on-stream-networks\/+spatial+statistics+arcgis+water&amp;cd=1&amp;hl=en&amp;ct=clnk&amp;gl=us<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Things I would like to accomplish by the next class period are to 1) download those two toolboxes and 2) see if they seem to work with ArcGIS10.
