Download spatial map file

But some are just available in raster format. Their data map shows the most available data is in the United States. But data is also available in Europe, Asia, and Australia too. For example, it holds more than variables such as freshwater, climate and health. I must admit. I found it a bit difficult to explore the GIS data because the interface takes a while to get used to. From here, you can download free GIS data like climate, disasters, and ecosystems. Imagine seeing daily snapshots of climate and environmental conditions of Earth.

For example, data ranges from aerosols, chlorophyll to sea surface temperature. Sentinel-2 is the highest resolution satellite imagery available to the public for free. Its interface is the Copernicus Open Access Hub. First, you have to register to create an account. Next, select your area of interest by right-clicking on the map. Finally, select the S2A or S2B product you want to download and download. So, be careful about what you choose to download. Terra Populus TerraPop for short integrates census data from over countries around the world.

In fact, it spans up to six decades for household-level and aggregate data for more than 80 countries. The unique thing about it is how you can explore temporal and spatial changes. But everyone can access changes in the human-environment system for geographic space. TerraPop also includes your basic land cover, land use, and climate data. Even now, updates keep rolling out. The focus of GeoNetwork is to improve global sustainable development.

For example, global agriculture, food security, and fisheries are some of its key free GIS data. Global Map still packs some serious punch with its free GIS data. Before you connect Before you can connect to spatial files, make sure to include all of the following files in the same directory: For Esri shapefiles : The folder must contain.

Then do the following: Navigate to the folder that contains your spatial data and select the spatial file you want to connect to. Select Open. Spatial file data source example Here is an example of a spatial file data source using Tableau Desktop on a Mac computer: Work with the Geometry column There are many tasks that you can optionally perform on your data before you start your analysis, such as hiding or renaming fields.

Note, however, the following restrictions apply when working with the Geometry column: You can't hide the Geometry column. You can't split the Geometry column. On the data source page, you can't create a calculated field using the Geometry column. Back to top. I love hex maps! Especially for the United States, you can keep states in a basic geographic orientation, but eliminate the visual perception problems caused by the fact that some states are huge compared to others and Alaska and Hawaii shift the scale when added.

But there are a few headaches that can occur when creating and using hex maps. And he inspired me to use one for my first time in the Iron Viz finals:. But, as Rody Zakovich noted, it is impossible to precisely control the size of custom shapes in Tableau.

So, Rody came up with a brilliant alternative: use polygons. This approach eliminates the sizing issue because Tableau does a great job of precisely adjusting the rendering of polygons based on the size of the view.

One thing I love about the Tableau community is how we inspire each other! Brittany Fong comes up with tile maps. Matt uses the approach as one way of creating a hex map, it inspires me to use it and Rody to come up with another way. And as I thought about it, I realized that there is a feature in Tableau that might offer an alternative to polygons.

I mean, sure you can render the current counties of the United States, but what about showing counties as they looked or years ago? And what if you had a spatial file that rendered each state as a hexagon. Look at those amazing geospatial options:. But in the end I had a spatial file that can be used in Tableau to render a hex map!

Do you want to use the spatial file yourself? Of course you do! Actually, here is an updated version with Puerto Rico! This is awesome! Thanks for uploading this. Could you write a tutorial on how to create a spatial file in Alteryx? I would like to display the Indian states as spatial hex map.

Thank you! Sounds good! I can send you the file if it helps. Those were all just trial and error to make the hexagons fit well on the projection.
