Hi All, I am looking for a citation for the interpolation algorithm used in the GeoEnrichment Service (e.g. this algorithm http://resources.arcgis.com/en/help/arcgis-rest-api/index.html#//02r30000021s000000) I have found http://www.esri.com/~/media/Files/Pdfs/news/arcuser/0114/MoreThanAPretty.pdf and an older BAO reference http://downloads.esri.com/support/documentation/other_/BA91_Block_Group_Centroid_Aggregation_FAQ.pdf I was hoping to find a citation in the "primary" literature not trade literature.  The primary literature I have found focuses on using boundaries to do the apportionment, not centroids.  Plus I have not seen any Census Block literature, only Census Tracts. Thanks ! -Don ... View more

Hi All, I installed ArcGIS 10.2.1 on my Windows 8.1 Pro machine and am having problems. I can open/display maps, and do many of my 'normal mapping' stuff. However, every single tool that I have tried in ArcToolBox 'crashes' ArcMap.  I put crash in quotes because it ArcMap just disappears. I had noticed that some people complained that newer versions of Python installed on the machine interfere so I uninstalled by Python 3.2.  I think that I am now using the correct Python (see code below). What else could be causing my problems ?  What seems odd is that when I open a command window and type 'python -V' it comes back as not a recognized command I typed the following into my ArcMap python window.  I believe this means that it is running correctly.  >>> import sys >>> for pypath in sys.path: ...     print pypath ...     C:\WINDOWS\SYSTEM32\python27.zip c:\program files (x86)\arcgis\desktop10.2\arcpy C:\Python27\ArcGIS10.2\Lib C:\Python27\ArcGIS10.2\DLLs C:\Python27\ArcGIS10.2\Lib\lib-tk C:\WINDOWS\System32 C:\Program Files (x86)\ArcGIS\Desktop10.2\bin C:\Python27\ArcGIS10.2 C:\Python27\ArcGIS10.2\lib\site-packages C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy C:\Program Files (x86)\ArcGIS\Desktop10.2\ArcToolbox\Scripts >>> print 'Running against: %s' %sys.version Running against: 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] >>> Thanks in advance ! ...

Hi All, I am curious to know if there is an efficient method to query all the sublayers of a map. For instance the USA Population Density (http://server.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Population_Density/MapServer) has data in sublayers at the State, County, Tract and Block Group levels.  If I had the Block Group level displayed, what would be an efficient method to query the same data (population density) at the Tract, County, and State levels ?  I am guessing that I actually need to query via the sublayer number (e.g. Block Groups (1), Tracts (2), Counties (3), and States (4)) Thanks in advance ! ...

Hi All, I need to explain to my managers the differences between Business Analyst Server and ArcGIS Server.  Could you help out ? Here are some differences that I know of (but I am by no means an expert). Data - BA comes with boat loads of Census and ESRI data Reporting - BA comes with pre-loading reports and the ability to easily make report templates Geoprocessing Services ?? Many thanks to all ! ... View more

Hi All, I am doing a bit of QC on a project and I want to automate as much of the process as possible in Model Builder.  Basically I am tasked with QC on a GME call isectpolyrst (http://www.spatialecology.com/gme/isectpolyrst.htm) So my Model zooms into a polygon feature calculate the percentage(s) of areas each of the raster categories and adds that as a new field (PercentArea) to the raster map. The output from isectpoyrst just adds to the percentages as attributes to the polygon.  The Field Name(s) come from the categories so if you had three categories in your raster file (1,2,3) your polygon will now have three new categories with the percentages.  My categories would be a200V1, a200V2, and a200V3). So my question is this ...  How do I 'join' the two results ?  [INDENT]Raster Map Attributes OBJECTIDValue Count PercentArea 1 7 5 0.002235 2 11 102 0.045597 3 12 1 0.000447 4 13 2051 0.916853 5 14 69 0.030845 6 15 9 0.004023 [/INDENT] Vector Map Attributes [INDENT] OBJECTIDa200V7 a200V11 a200V12 a200V13 a200V14 a200V15 17953 0.002235 0.045597 0.000447 0.916853 0.030845 0.004023 [/INDENT] So you can see that the Attribute Fields of the vector map is related to the Values of the raster map. Basically I need to match these values up so I can do a simple difference by adding a new field to the raster map and then updating it with the appropriate vector map attributes.  [INDENT]Final Raster Map Attributes OBJECTIDValue Count PercentArea VectorPercentArea 1 7 5 0.002235     From Vector Map 2 11 102 0.045597 3 12 1 0.000447 4 13 2051 0.916853 5 14 69 0.030845 6 15 9 0.004023 [/INDENT] Any ideas on how to accomplish this in Model Builder ?

Hi All, I am trying to load my custom BDS into BA Server and am experiencing difficulties. The first window after Upload Project ...  asks 'Select Business Analyst Server' and for the life of me I cannot get anything to work.  The BA server is here:  http://v18ovhrtay724.aa.ad.epa.gov/ArcGIS/baserver/REST/services/DefaultMap/Default.aspx and I have tried all sorts of permutations on how to connect to it but I cannot. What *exactly* do I type in here ?  Also, does this need to be in the Business Analyst Server Connections (as seen in ArcCatalog ?) Thanks ! -Don ... View more

Hi All, I am starting to learn BA so this is a newbie question. I have some of my own data that I want to use in Business Analyst and the data is at the following scales:  Census Block, County, State So what I would like to do is bring this into BA and then allow BA to interpolate at scales in between these three but when it is at those scales to use that data.  I have imported my county data following the steps at the Blog Series here http://blogs.esri.com/esri/arcgis/2011/10/12/blog-series-1-of-5-kyle/ I decided that i should have no aggregation during the BDS set up because it seemed to me that was what I should do. Anyway I am a bit puzzled on how to set up this BDS so I can begin working on it.  Any help and/or links would be appreciated. ... View more

Hi All, I have a few questions regarding spatial logistic regression. First off, I need to make sure that this is the correct model to create.  Here is what I want to do:  [INDENT]  I have a binary variable that is polygon based that I want to predict (Flood/Not Flood). I have a soil polygon map that has data associated with it (e.g. percent soil type, landform etc., there may be other data that could be helpful but let us wait on that).  So the soil map is by counties and some counties in a state are mapped, others are not and same thing with my flood data.  I want to predict flooding in the areas where I have no flood data. The soil data has a very strong spatial component to it (some states do not have certain landforms, counties are soil mapped differently etc.).  I have tried a simple classification model (e.g. all polygons where landform ='XXX' are flooded) but the performance is not that great at the state level.  So I figured I could create a model that is spatially aware and varies through geographic space.  To me, this means I need some sort of spatial logistic regression model to predict the probability of flooding based on a certain amount of variables.  [/INDENT] Q1:  Is Spatial Logistic Regression the 'best' type of model to perform flood predictions ?  I think there are others (e.g. Spatial Bayesian predictions).  [INDENT] I've seen some chatter in the forums over the last couple of years regarding software to allow users to do this and want to check on the status of software tools to help you accomplish this. [/INDENT] Q2:  What kind of software can help me with this?  I am very familiar with R so I could certainly do that.  I've not tried PySAL yet so that is an option as well. Q3:  Has this kind of thing been done with polygons ?  I wanted to check before I went to far.  How does the polygonal nature of the data change how the model behaves (e.g. are the equations weighted by polygon area and geographically?) -Don ...
