I worked on updating some USGS quads, back in the 90s. It seemed like most of the style guidelines were published internally, long before the Internet, and never made it online.
It's fairly common to show two sets of State Plane Coordinate System grid tics on quadrangles that are near a boundary between two zones. With UTM zones, it isn't such a big ...
DLG (Digital Line Graph) format is not a valid OGR data source (it can be corroborated in OSGeo4W shell with ogrinfo --formats command). So, you need a data converter for DLG vector files. This coverter can be downloaded from here: https://esri.box.com/v/sdtsdlg2shp .
At following image, you can observe its GUI.
Into unziped folder, there is User’s ...
This can be done in QGIS using two custom line styles (see the bottom of this answer for the two style files you can import into QGIS):
While it might seem like the "Light Duty Road" (two parallel black lines) could trivially be implemented using two thin offset lines, you will run into trouble with this approach if you try to display ...
There are other options to download Landsat7 images. Here's what I do:
Go to EarthExplorer and click on register on the upper right
corner to create an account.
Then again go to EarthExplorer and log in with the account that
you have just created.
In the first tab Search Criteria, you can set the acqusition time
and area of the data by different ...
I just downloaded a Landsat 7 Surface Reflectance scene from USGS EarthExplorer. It contains QA bands.
If you are ordering from the USGS ESPA, CFMask should be included by default in the Surface Reflectance product, but can be ordered separately (tick the CFMask box).
As long as each dataset you are adding (elevation and imagery) has the correct grid information, QGIS will be able to project both datasets properly. If they cover the same area, than you will have the map-matching you are looking for.
Install QGIS, then add your datasets. That should work out as you are interested in.
You might need to get Machine-to-Machine access to use third party libraries which are based on this API. To get access you have to send request to USGS EROS User Services: firstname.lastname@example.org
Here is required information to provide Machine-to-Machine access:
To be considered for authorized access to data held in the USGS EROS
archives, we need to obtain ...
The "TL" stands for Tribal Land. These areas are coincident with tribal lands and were pulled out of the original project in order to await approval from tribal authorities before publishing the "TL" part of the data.
If you download Collection-1 Landsat Images, both Landsat 7 and Landsat 8 Higher Level Data Products will come with pixel QA band. Otherwise you need to download the CFMask which has the same information but calculated with a different algorithm.
For more information you can check https://landsat.usgs.gov/landsat-surface-reflectance-quality-assessment ...
The difference that you see arise from having a mix of 'surface reflectance' data, and 'uncorrected' / 'raw' data.
The scenes with a MTL.txt are 'uncorrected' while the ones with the xml files are 'surface reflectance'.
I am uncertain as to why you have a mix of the two data types, but something must have gone wrong in the ordering or the processing of data.
Just looking at your image src attribute value, I can see that you have a few errors:
<img src="<wms server>?
Those are National Geographic Maps (basemaps)
Note: You need to select Terrain in the Maps Layers on the USGS Earthquake site
you can view them via USGS via:
One way is to use the Define Projection Tool in ArcToolbox (or the raster's property page in ArcCatalog). I would pick a related projected coordinate system as a start point.
Browse to Projected Coordinate Systems, Continental, Africa and choose Africa Albers Equal Area Conic.
Right-click and choose Copy and Modify
I would change the PCS name.
Update the ...
The data can also be downloaded for the National Map (as part of the 2011 NLCD dataset), but it's in 3x3 degree segments so there are 131 parts to download. They can all be downloaded at once if you use the Download Manager. Multiple people find the download from the USGS NLCD website slow, so it's probably an issue with their server.
Rather than using individual US Topo quadrangles (which are designed to be displayed in that format), you can download the underlying vector data from The National Map and customize the extent of your display. (There is also a style sheet available to match the symbology of US Topo maps, although this is an ArcGIS-specific format and I don't know whether it ...
Did you try loading it as a WMTS layer? In the Data Source Manager, use the WMS/WMTS tab to set it up. Or choose Layer->Add Layer->Add WMS/WMTS Layer. Use the following URL:
The original USGS 7.5-minute (1:24,000 scale) Historical Topographic
Maps (produced 1945-1992) included feature classes that are not yet
shown on US Topo maps (produced 2009-present). Examples include
recreational trails, pipelines, power lines, survey markers, many
types of boundaries, and many types of buildings. The USGS no longer
The website always sends DEM files that are 1° wide and 1° high.
If you want a smaller area, you have to clip the downloaded data to a bounding box rectangle you need. Every GIS software is able to do that locally.
As commented by the asker, the answer from USGS was:
I've looked carefully at these data and the files available, and it
seems we have no style file nor any explicit relationship between unit
symbols and colors. My guess is that the PDF map was composed in Adobe
Illustrator using the linework provided by ArcInfo version 8.0. In
some of our older ...
The only satellite with hyper-spectral imaging capabilities that I've been able to find is EO-1, which has the Hyperion spectrometer you're referencing.
There could potentially be satellites that aren't in the public eye with such capabilities, perhaps military satellites, but I certainly haven't heard of any.
Perhaps multi-spectral imaging would work for ...
I downloaded the PDF from your link and used your gdal_translate command. My QGIS 2.16.2 opens the converted tiff file correctly with reasonable coordinates at the top left corner. It feels like it is your QGIS installation that has some issue.
Use "x <- sf::st_read" it's much faster than rgdal and will happily read much larger data sets.
When you plot it, be sure to use "plot (st_geometry(x))" first, since it will otherwise do a lot of repeated drawing for the default multi panel layout. It defaults to faceting on every column, up to some max.
Indexing with "[" works the same as with sp, so ...
You are on the right track. You might want to select Landsat Archive instead of CDR and select any additional criteria such as percent cloud cover etc.
Landsat CDR refers to Climate Data Records. See - https://pubs.usgs.gov/fs/2013/3117/pdf/fs2013-3117.pdf ; whereas Landsat archive gives you a host of land cover related products from 1972.
My best advice is to follow the instructions provided by the GDAL devs at https://trac.osgeo.org/gdal/wiki/USGS_PDF_Topo
It contains a python script to extract the neatline from the PDF metadata.
Unfortuantely, the neatline is too large, it includes the grid coordinates. So you can do this:
run python config.py yourfile.pdf inside the OSGEO4W shell
Any of the USGS Topo Map Services from an ArcGIS Server instance can be consumed in QGIS via a WMS service.
For example, this web map: https://www.arcgis.com/home/webmap/viewer.html?webmap=931d892ac7a843d7ba29d085e0433465#!
...comes from this service: https://services.arcgisonline.com/ArcGIS/rest/services/USA_Topo_Maps/MapServer
