Spatial cover breakdown question
Spatial cover breakdown question: I have a shapefile of landscape characters (polygons) and a shapefile of land cover classes (polygons). Both are of the same region, i.e. they overlap. Is there a tool to obtain a breakdown of the spatial cover of all land use polygons within each landscape character polygon? Ultimately,…

How to relate pixel count per tesselation
***I AM USING ARC MAP 10.8*** I am trying to finish an NDVI analysis of an area pre/post hurricane Harvey. I have run the NDVI to gather my values and they have been reclassified to follow the values of, 0= (-1.0 to 0.29) and 1= (0.29 - 1.0). The reclassified raster attribute table is attached as the 2016_Classy.PNG file…

Besides reducing processing time, is there a benefit to creating an LAS dataset versus working with LAS files directly in ArcGIS pro?
I am a masters student working with LIDAR and 4 - band satellite imagery to remotely measure above ground biomass of the shrub community encroaching the Illinois Lake Plain region. I am new to working with LIDAR data, and I am contemplating if creating an LAS dataset is necessary or if I should just import the LAS files…

error 010328
I have ArcGIS 10.7.1 software. It works perfectly except for image classification. Whenever I use I image classification algorithms I get same error message "Error 010328: Syntax error at or near symbol space". I changed the name of the file to be classified but the error remains there. Also, I changed location for saving…

I'm new to ArcGIS and have a question about performing canopy coverage analysis.
Hello all, I need to update a canopy coverage analysis that was originally performed in 2009 using photos from 2008. Newer photos have since become available, and I have been asked to update the canopy coverage analysis maps and interpretations for a local planning department. Specifically, I have to re-run the percentage…

Zonal statistics for land cover analysis within vector polygons
What I’m trying to accomplish is simple to define: what is the percentage tree cover (raster) across four polygon zones (vector)? When I run my analysis using Zonal Statistics as a Table, I get an equal ratio of tree canopy in each zone (Count/Area). Each zone seems to have 25% of the total tree canopy count, but this…

generating training sample schema in Arcpro
Hi, I am attempting to create a training sample schema for an image classification in ArcPro. I created my own training samples in the form of a file geodatabase feature class and am attempting to upload that feature class into the training sample manager. When I select the "generate from training samples" options in the…

Clip tools inconsistently working and not clipping data
I am trying to clip a large land use .img layer to a buffer polygon shapefile layer. I need data to be exported with the clip because I will be using it for an analysis. Whenever I use Clip (data management), the resulting layer does not clip any of the raster. When I use Image Analysis, the clip feature only occasionally…

Automate dataframe fitting to grid
I am using Arcgis 10.2.2 and preparing some data for printing and im stacked with something. I want to autorotate the dataframe on the grid (which grid after grid it gets rotated by some degree) cause i am using data driven for printing content inside a grid. The red rectangle is the limit of the grid where the data should…

Learning how to extract land cover data
Hello, I am wondering what resources or training are available to learn how to extract land cover data from orthophotography. Almost all of my GIS experience is with vector data, I have never done much with raster data beyond displaying it as a background to a map. I am working with an urban forestry nonprofit right now. A…

Adding base layer
I am trying to add a base layer however when I select add data and the drop down menu pops up it will not allow me to select the base layer option. I have added a layer through Arc Catalog through the GIS Servers menu so I am assuming it is a problem directly with adding a base layer command. Thank you.

Proper Tool for Creating a 3x3 Window for Cluster Sampling In Accuracy Assessment?
I'm using a cluster sampling scheme for an accuracy assessment of the 2011 National Land Cover Dataset (spatial res of 30m). I'm using Google Earth Pro for my reference data spatial res of 15m). So far I've generated random sample points for each land cover category (the number of sample points generated for each land…

Creating a Grid For A Raster When Measuring Land Cover in Accuracy Assessments
I am assessing the accuracy for the 2011 National Land Cover Map (NLCD). Each pixel for the NLCD measures 30m x 30m. For my reference data, I'm using two sources: 1) Google Earth (~15-20 m resolution) 2) NAIP hi res imagery (1-2 m resolution) For each randomly sampled point I've created, I want to create a grid that lays…
