Download equal area projection file






















Style it and optionally set scale-based visibility ranges if you want varying levels of detail at different zoom levels. Then create a vector tile index. This makes the resulting tiles really efficient since it only adds detailed tiles high-density content exists.

Or something like that. This may take some time longer than actually cooking the tiles , depending on how complex your vectors are.

FYI, it looks like this. If you open your index layer to take a look, just remember to remove it before you cook the tiles next.

Then run the Create Vector Tile Package tool. I left the scales at default, but best to max them out. Then fire up the engines! And let it run. Creating vector tiles is a reasonably quick operation.

When done, you can drag the resulting tpkx the tile package file that holds all the rules and data file into Pro to verify everything looks the way you want just remember to turn off the original layers so you are actually seeing the tiles. And there it is. Click on the Select CRS button. We choose Albers Equal Area Conic projection for this tutorial as it is a popular projection choice for thematic maps of the US.

The choice of projection for your particular use-case will depend on a lot of factors. See this guide for a good overview of Projections. You will see the new CRS selected in the Save vector layer as… dialog. Click OK. Switch to the CRS tab in the Options dialog. Click on the Current CRS text at the bottom-right corner.

Now you will see the United States in the selected projection. You will notice that the. That means they do not have any projection information. To use these images in a GIS, you need to georeference them. A georeference contains 2 types of information - image extents and projection.

Typically, the extents are stored in a file known as World file and they have extensions like. If you are deciding whether you want to pursue a career in civil engineering, you are probably wondering whether civil engineers are paid well. Although one should consider a number of things such If you are reading this article, you may be considering agricultural engineering as your area of study.

If this is the case, this blog post will give you a more solid understanding of what life is Geographic Coordinate System A geographic coordinate system represents the Earth using a three-dimensional 3D spherical surface. Geographic coordinate systems are also called global or spherical coordinate systems.

Projected Coordinate System In contrast to a geographic coordinate system, a projected coordinate system is based on a map projection. Some of the most common types of map projects are discussed below. Equal Area Projections An equal area projection is designed to maintain the area of specific features. Conformal Projections Conformal projections maintain the shape of a small area.

Equidistant Projections An equidistant projection maintains the scene along one or more lines. Azimuthal Projections Azimuthal projections plots preserve the direction from one point to all others.

For this projection, each great circle is mapped to a straight line. Seismologists frequently use this projection because seismic waves travel along circles. It is also a projection that is used for navigation.

This is one of the oldest map projections used today. The gnomonic projection is not equal area or equidistant. These two properties increase as you move away from the center point.

Stereographic This projection maintains direction from the center point. Each line represents a great circle. The stereographic projection is not equal area or equidistant. Orthographic The orthographic projection involves projecting the globe onto a plane with the point of projection as infinity.
