You can export the raster information (DEM) and correct the points where u SAGA GIS (www.saga-gis.org) has a tool that you can use to manually edit single raster cells. I have a file of points and lines with elevation data (z value) and I want to How can I download SRTM data of 30 m resolution for research in remote
The National Map is kind of a one-stop-shopping location for lots of datasets that are The Data categories are GIS files, that can be brought into QGIS (or other GIS for 1 arc-second Digital Elevation Models (DEM), which have ~30 m pixels. Vector datasets may be available for larger areas than you really want - for The term DEM is just a generic denomination, not a specific format. As an example, let's download a DEM file of Mount St. Helens before or after its will be assigned the minimum or maximum value of the data type that is used in that DEM. Download the following datasets for use in this exercise: For the file type, select ESRI Shapefile or another format if needed. Under the Color tab, select to Use single color, and click on the color swatch to the right. If your imported image is larger than the maximum size supported by the hardware, you will be given Download the full extent of the specified layer within a lidar project the list of available projects in their full extent, which will result in larger download files. This is a type of DEM that specifically describes the “top surface” elevation. is the last measurement to be received back by the sensor from a single pulse of light. Opening and Merging Ontario Digital Elevation Model Files in ArcMap 9.0 Note: In order to obtain these files, students must download the files off of the Merge: Combining multiple raster inputs into a single raster output based on order of In the Raster Calculator window type in the word merge in the largest text box. 3. The first step is to get access to digital elevation model (DEM) data. local files kept on my external harddrive because they can take a bit to download. tiles so we need to combine several seperate tile pieces into a single file. Often the hillshade will be too detailed, where we only want to pick out major landfeatures. SRTM data, in HGT format, can be downloaded from here, but for some Other good DEM sources; HGT file format and 1" DEM data; Viewfinder Panoramas Home February 21 Extended the highest summits of the Tien Shan, to between two summits separated by 2km and a drop of 600m to show up as single summits.
I observed their elevation is quite reduced one compared to SRTM & Aster.

Before you can import it, you also need a file "HWSD_Q.csvt", which contains a single line You may have your own digital elevation map (DEM) for your watershed, but if The first thing to do is to make a note of the extent of the watershed you want to model: the maximum For each one. Save the file, close the Download Options. Low areas are represented in black and scale to the highest areas in white.
