SUM LENGTH OF LINES IN POLYGONS

Hi. I have over 10 000 polylines spread over 430 polygons. I would like to sum the length of all polylines within each polygon. Do anyone know how I can do this in ArcGIS 10? I tried Hawth's Analysis Tools for ArcGIS, but it does not work with ArcGIS 10. Any help would be great Thanks.

CLASSIFICATION: UNCLASSIFIED Do you know Python? I so you can use the Python API and write a script to filter your table on road lengths and road types and then use the Pandas and Seaborn libraries to make a histogram. I have also seen a new little set of libraries called plot.ly but I haven't used them yet. If you don't know Phython, I…

Forest-based Classification and Regression stuck at 0%

Hello, I'm trying to run Forest CART in ArcPro 2.4, with about 8 explanatory variables trying to predict the 9th variable. The setting up of the tool runs with only warnings, then proceeds to Create Trees. However, Create Trees is stuck at 0% - I left it for over 2 hours, and it remained stuck at 0%. See below tool parameters: Since… (Show more Show less)

Arcpy rejecting outputs of recursive math expressions/python methods

9/10 spatial analysis I do involve mathematical expressions. Users want me to execute recursive math functions,to aid spatial analysis and clustering. I have challenges passing such expressions into arcpy.da and Code Blocks in calculate field. A simple case in point; I have the table below. I need the code to recursively calculate minimum start… (Show more Show less)

I therefore thought, that mayber the unique identifier field wasn't set. Searching the Arc GIS Help Ressources I found this site that tries to explain how to set the Unique Identifier.… (Show more Show less)

This was asked long ago, but I just ran across the same problem. My fix is very roundabout, but it did work. It only works for point feature classes and assumes that you want to use sequential integers starting at 1, but just in a different order than the ObjectID you have already. Use the Add XY Coordinate tool to add coordinates to your…

How the GWR count their Weight?

Hello! My study is about evaluating the correlation between flower production and weather parameters. My data are taken from 2015 - 2018 in form of point data. The point data is the greenhouse location, which only includes 9 greenhouses. In each greenhouse has 400 attribute data (flower production and weather parameters) observed within weeks… (Show more Show less)

Kriging vs Spline with Barriers

Hi, I'm Jeniffer Soto from the Biogeochemistry group at USGS. We want to create a prediction surface for different water quality parameters along the Sacramento-San Joaquin Delta. Predictions are currently being completed using Kriging/Cokriging (we determine which is the best method using the summary report), and Spline with barriers. These… (Show more Show less)

Regression/OLS for point data?

I have been looking around online and whenever I see reference to OLS or GWR, few to no one using point (x,y) data in their tutorials. Why is this and is there a way to do a "what is the relationship between these variables" analysis without attaching the x,y point data to polygons. I am comfortable making grids or associating individual points… (Show more Show less)

You can absolutely run regression analysis in ArcGIS on point data. You will need a dependent variable and explanatory variables for every point.

Using the Forest based classification and regression tool, will there always be created a new trained model with every prediction or is the first one automaticily used?

When creating a prediction, i wonder where to use the output with the trained test data to generate a predicton of the actual data. So, will there be always created a new model and used on the actual data or is it stored in the background and used when creating a prediction without specifing the model to use? If i want to use the trained model for… (Show more Show less)

I just updated to ArcGIS Pro 2.3.2. The Optimized Hotspot Analysis tool is giving me the following error. I've been running the same parameters for a few months now and this is the first time I've had this issue, and only after upgrading. Is there a way to fix this?

Projecting the data has fixed the issue, though I'm still not sure why. I'm only running the tool on a single city with the city boarder bounded, roughly 20x25 square miles, and the tool ran successfully when the cell size was not set. Which probably would have been fine, except for there being no cell size consistency between several maps I…
