Thank you dear Lurker

Dear all I want to extract a raster values to a very heavy point shapefile (with 1.700.000 points!) in ArcMap. It takes very long but only uses 37% of my memory? How can I allow ArcMap to use more memory to save my time? http://s4.picofile.com/file/8286974650/photo_2017_02_19_20_36_46.jpg

problem persist with ArcGIS 10.4.1. Drivers of my Intel and NVIDIA graphics are the latest version.

All of my drivers are up to date!

Hi all I recently renew my Laptop with a better one with windows 10 platform, but I have a problem with some software such as arcgis 10.2.2 In the software environment, icons are really small. when I change arcmap setting to big icons, the size of icons getting bigger than normal condition in the past! please help me. I like normal view of arcmap.

Google it. It's free software.

SASPLANET is very useful

Exactly, Thanks friend.

this tool is for exporting images and vector files to google earth. i want to link envi and google earth lively.

Dear All I want to use supervised image classification method in ENVI 5.3 and I want to link image in ENVI with google earth for accurate training data selection. I can't find this in ENVI. In Erdas Imagine this is really easy to link image with GE but in ENVI i can't find!
-
yes, I tried an image from 1985 and second from 2000. both from landsat. in both images I have problems in urban area and barelands. Thanks
-
But only minor improvements in urban area.
-
Dear deepgis Thanks for your comment. you are right. I used reflectance data for calculating NDVI, NDWI and SAVI too and then combine them with 3 component of PCA of bands, as layer stack in Erdas imagine.
-
any more suggestion?
-
Dear deepgis I used 3 PCA components of band, NDWI, NDVI, SAVI, 3 Tasseled Cap components all extracted from ETM+ band: 1,2,3,4,5,7 instead of raw bands. But i got only minor improvements in the results. Still in supervised and unsupervised barelands and urban area mixed together. Please help me
-
Thanks for your comprehensive answer. I will try NDBI, NDVI, NDWI and such indices instead of raw bands of landsat in Suoervised and Unsupervised methods.
-
Dear lurker I have tested various combinations but some of bareland recognized as urban area in both supervised and unsupervised methods. How many bands is enough for image classification? I used all 7 bands as layer stack.
-
Thanks for useful information. I use landsat 7 because i need time series of images from 1985 to 2005. I tested Erdas imagine 2014 and Terrset for classification.

How import Sentinel-2A bands in Erdas Imagine
