Converting netcdf on native structure to lat-long for GIS
Hello! I am currently working with large oceanic model outputs structured as netcdf files (ROMS for anyone familiar with physical oceanography). Ultimately I would like to seamlessly import them into ArcPro. The catch: the coordinated of the netcdf are native (we call them xi, rho) instead of being lat, long. Additionally,…

unusual merge
I need to reorganize my data. to do this i need to merge points in a particular way. i need to merge the data from points that have less records to the point with most records inside a 5 km buffer created around the latter. the problem is that to generate that buffer i need to find all the "points with most records", but…

Help! i need to create spreadsheet of points...
So i am new to Arcmap. I am trying to generate a spreadsheet with coordinates and id of points within a certain radius of other points, but i can’t find how to do this anywhere. I’ve tried spatial join, i’ve tried select by location. It only gives me the number of points or the sum of all point inside all areas, which is…

Displaying data (Voxel Layer)
Hi, We got some raw data which would be converted into netcdf format, and visualised by using voxel layer. We are exploring methods on making boreholes so that the voxel layer would be like a underground pipe in ArcGIS Pro. Is there any suggestion or example similar to this case? Thanks a lot!

Looking for specific CSV data.
Hey Esri Community! Hoping y'all can help me out. I'm working on mapping temporal data, but I'm running into issues finding the proper CSV data. Does anyone know where I can find files on : 1.) magnetic pole locations over time 2.) location of solar incidence over time 3.) ocean and land temperatures over time I'd greatly…

How to get time dimension for Sentinal-5P TROPOMI L2 NO2 netCDF recognized in mosaic dataset in ArcPro?
I am loading netCDF files from L2 TROPOMI Sentinal-5P into a mosaic dataset in ArcPro. It is not recognizing the time dimension correctly. ArcPro seems to recognize time as a dimension, but not parse it correctly. The definition is ‘seconds since 2010-01-01 00:00:00’. The data are daily, so the time steps should be 86,400.…

Series of raster maps, how many times x pixels within basins beyond a y threshold?
I have a huge series of raster maps in which the pixels vary their value (from 0 to 100) from map to map. Then I have a watersheds map (i.e. a map divided in subareas, shape or raster). How could I do to count how many time in each watershed (subarea) x pixels exceed a certain threshold (for example at least 3 pixels…

Categorical variables while using Geographically Weighted Regression (GWR)
Hello! I have a question regarding Geographically Weighted Regression (GWR) in ArcGIS. So, I am using ArcMap 10.2 version. I have a large dataset of different parameters of groundwater geochemical constituents and physiography. In GWR model, my dependent variable is chemical concentration (continuous variable) and one of…

Polgon to raster issue
Seems unlike the older Email ESRI list no one responds to Geonet questions. I need to update ASCII files with new data for spatial distributions mapping of critters. I have created the new polygons, in this example distance from caves as a buffered set of polys. Using 100 m intervals from 0 to 5K m. The new shp file looks…

Why do imported table values display incorrectly once added to geodatabase?
When I import a CSV or TXT file into my geodatabase the cell values for a specific field do not display correctly. CSV format - only 2 fields: Import options. It seems to be creating fields based on historical fields from data not even inside the geodatabase any more Whether I delete these fields, keep them or change the…

How to interpolate weather data
Hello, I'm looking to create an interpolated surface from 5 weather stations spread throughout southern Ontario. The stations are roughly equidistant from each other, and have temp & precip data for the exact same times. Before, I typically used the Kriging tool inside 3D analyst. This time when I try it, it simply creates…

Model Builder - Summing daily rasters by week
I have a set of about 150 daily rasters derived from MODIS images (to start with, really 16 years worth). I want to make a model that will take seven at a time and sum them, so there is a weekly summary. I am working with model builder, and I think I have several sub-tasks: * Select seven rasters * Run them (with Feedback)…
