To show you how simple it is to add tilemap layers to QGIS I will use the example of OpenTopoMap a layer that was asked for in the comments of my previous post. Normally this URL contains at least placeholder for x, y and z. In the example of opentopomap, a quick google search guides me to the OpenTopoMap page on the OpenStreetmap wiki. The last paragraph shows how OpenTopoMap can be used:.

The more we zoom in, the more tiles we get.

Values normally refer to the tile number form an origin point. Look for the browser panel in the QGIS interface. A context menu will open that allows you to create a new connection. Selecting this function will bring up a window that allows us to enter the previously found URL for our service.

Now that you service appears in your list of tilemap server you can now double-click it to add the layer to your project. What does that mean for you? Do you have any suggestions for accessing tiles stored locally on disk? Interesting question… unfortunatley after some first quick trials I failed as well.

Will have to investigate a bit further — but please let me know if you find a solution….

Below are a couple more tile connections I have tried that are handy. This is my first post ever so let me know if these work for you. Is this because or the brackets? I am new to this stuff. Is there still no solution for using tiles stored locally on disk? For this we generated tiles with QTiles- Plugin, which worked really well. This is something that I always wanted to test, but have not found the time to investigate.Sincethe purpose of these general use maps has been to display the complex, changing geography of the United States.

This includes hydrography, place names, contour lines and cultural features of the nation. Otherwise, you can download the raw vector and raster GIS datasets in the bottom option. By default, your current extent is the search area. However, you can enter latitude and longitude coordinates or draw a polygon extent to change it. Also, you can filter by date period in the advanced option. Unless you want topo maps in Alaska, they are based onandscales.

One of the neatest things about USGS topographic maps is how some of them date back to Simply, move the time slider and it will filter and preview the Topo maps. Similar to the TNM Viewer, add items to your cart that you want to download. In order to do that, you have to click anywhere on the map. In addition, you can preview the topo map in the viewer which is a neat function. Because you can preview images and filter with a time slider, these qualities make TopoView extremely intuitive for the end-user.

If you have any GIS software installed on your machine, you can consume web mapping services like these National Map Service Endpoints. All you have to do is add these URLs to your map. When you just want physical prints, you can visit the USGS store to get them delivered at a cost. Overall, the natural and physical landscapes in the USGS topo maps have become an extremely valuable basemap source of data.

Check out these sources and see for yourself. In order to run a search, you will need the parcel fabric with these IDs in them. Which state are you in?For this purpose, please use one of the Editors. Right clicking on that reveals an option to add that as a layer. See this screenshot. Note that QGIS caches the raster maps.

This includes all newly created nodes. QGIS should no longer be used before a major version release to support bit integers for nodes; it is possible that data retrieved from the database contain new nodes that would be truncated to 32 bits.

This would severely impact the database if it is updated with QGIS. Users should use another editoruntil QGIS 2. QGIS 2. More details here. However, due to a bug related to bit Identifiersnewer data is not read. There are an increasing number of QGIS styles pre-prepared and available for Openstreetmap data - for example:.

See also wikipedia:Quantum GIS. The QGIS wiki provides numerous guides and video tutorials to help users of all abilities. It is also important to have a basic understanding about the Coordinate Reference System. QGIS allows you to to create advanced symbology similar to Mapnik or Osmarender in a powerful but very easy way a few mouse clickssee examples here [ dead link ] and a detailed video on youtube.

Earth is a three-dimensional body, roughly spherical in shape, yet the vast majority of maps are flat 2-dimesional. Some, such as WGS are global projections, whereas others represent only specific regions. When working with geo-spatial data it is essential that you are using the correct CRS. If you are lucky the projection will be specified as part of the vector file for example, ESRI Shapefiles often include projection data in the. Each layer can have a different CRS.

If this is the case, you will need to convert them to the same CRS in order for them all to display correctly. The easiest way to do this is to use 'on the fly' CRS transformation:. More information can be found in this video tutorial. Open the input layer making sure to select the correct CRS as described above. In Sweden multiple government agencies give out data in large shapefiles. Here is a video tutorial describing more advanced filtering based on attributes.

Google Play.If you are like me, you probably spend a decent amount of time in your GIS software, right? Talking about visualization you probably want to have some good looking basemap in addition to your plain vector layers. Of course the very popular Openlayers plugin is great for that.

It easily integrates in your QGIS menu and will give you the option of adding the most common basemap layers to your project.

Unfortunately though there is not much you can adjust afterwards. One of the most common things I would like to be able to do is to add some layer transparency which unfortunately is not possible.

This is were GDAL layers come to the rescue! I stumbled upon this blogpost while looking for some new WMS layer that I could use.

Awesome basemap layer for your QGIS project

First an xml-file has to be created which can then be added to your QGIS project like any other regular raster layer. Why go through all this trouble? The GDAL layer that you just added will now allow you to change all properties like you would do for any other raster layer. Quickly I realized that it is crucial to know the exact parameters of the service used and how to correctly add them to the xml-file.

Luckily the GDAL website explains the structure of the file in detail and even gives some examples there. Browsing through various services I decided to pick some and turn them into GDAL xml-files so that I can use them as basemap for future projects. My absolute favorite is the SRTM layer — this will make things so much easier as I will no longer have to download different tiles for my projects anymore….

Feel like giving them a try? Of course there are endless more that could be created. What do you use as basemap for your projects? Any specific layers that you want to see as a GDAL xml-file? Let me know in the comments below….

These layers are not created by me, rather I use existing free layers and create the GDAL xml-file for them. Would you have any example of a WMS- or Tileserver that has the map style you are looking for?

It would be great if the zoom levels for the services could be defined in the xml files. Making the tiles draw at only the zoom levels they were designed to be viewed at instead of getting a pixelated or fuzzy image for scales between publish zoom levels. Hi, fisrt of all thanks for sharing! I can not load the xlm files, waiting about 5 minutes and after that qgis crashes. Any suggestions?

Once you re-create a hillshade, following the previous tutorialyou can head to the next step note that brightness and contrast settings may be different due to changes in how QGIS generates and displays hillshades.

Notice QGIS 2. Also, open the url in a browser such as Firefox, it brings up a webpage that describes the layer. We also see links to other other layers. Name the layer World Hillshade and click Connect, then click and highlight the layer it connects to. Finally, click the Add button to add the layer to the canvas. Next, we need to adjust the properties of the World Hillshade layer to properly overlay it above the SRTM hillshade layer. Make sure the World hillshade layer is the topmost layer.

Next, change the Layer Blending mode under color rendering to Overlay. You may also have to change lower the Min value of the Min — Max value boxes. Leave the contrast at 0 for the SRTM hillshade. We see a parallel array of roughly north-south orientated lines, these are fractures and faults that cut the Slieve Gullion Complex that were perhaps enhanced by glacial erosion. Also, look carefully, there seems to be some roads meandering across the landscape hint, bottom of the map and right of the scale bar.

You should get even better results with higher resolution World Hillshade data. We also notice that bending SRTM derived hillshade with World Hillshade adds a naturalistic illumination not apparent in multi-directional hillshading. So we have the best of both worlds, a high resolution hillshade and realistic looking illumination.

Baxter, S. Geological Survey of Ireland, Dublin. Jet Propulsion Laboratory, the U. The raw radar data has been continuously processed and improved since it was first collected. Countless artefacts have been painstakingly removed and areas of missing data have been filled using alternate data sources. It is therefore necessary to apply a suitable colour ramp that accentuates topography.

In the window that pops up, choose the full opt-city package and click check for update. The plugin will then download the cpt-city library, a collection of over a hundred cartographic gradients version 2. After the package downloads, quit the dialogue. In the Style tab, change the render type from single band grey to single band pseudocolor. Then click new color ramp and new color ramp again, choose the cpt-city color ramp to bring up the cpt-city dialogue.

Click topography and choose the sd-a colour ramp. While this is an excellent colour ramp, I find its colours are a bit too strong for my liking.

Next, change the brightness to 30 and lower the contrast and saturation to Click OK to apply the new style and quit the Layer Properties dialogue. Next we need to create a Hillshade layer from the DEM, a 3D like visual representation of topographic relief.

We need to enter a scale correction factor of in the Scale ratio vert. Once that is all done, select an output path to save the generated hillshade and click OK. Generating a hillshade may take up to a minute depending on the size of your DEM. After the hillshade is created, open its Layer properties dialogue.

Change the min and max values to andincrease its brightness to 45 and contrast to Finally, switch the blending mode from normal to multiply.
