Coordinate system – ArcMap and Mapinfo

Which coordinate system is used in ArcGIS?

Coordinate systems can be defined in both maps and scenes. In a new, empty map or local scene, the default horizontal coordinate system is WGS84 Web Mercator. For global scenes, the default horizontal coordinate system is WGS84.

How do you match a coordinate system in ArcGIS?

Right-click the data frame name and choose Properties to bring up the Data Frame Properties dialog box. Click the Coordinate System tab and navigate to the desired coordinate system for your map display.

What GIS coordinate system should I use?

Use a system that works well with your maps



If you are working with maps that cover more than 6 degrees of longitude or are 1:1,000,000 scale or less, you will probably want to use lat/lon coordinates. Small scale maps are often projected using a map projection that will result in UTM grids that are not square.

How do you add a coordinate system in Arcmap?

Create a coordinate system

1. In the Contents pane, right-click a map or scene and click Properties.
2. On the Map Properties dialog box, click the Coordinate Systems tab.
3. Click the Add Coordinate System button and click New Geographic Coordinate System , New Projected Coordinate System , or New Vertical Coordinate System .

Does ArcGIS use WGS84?

20054: Your web layer will use the WGS 1984 coordinate system—ArcGIS Pro | Documentation.

What are the 3 coordinate systems?

There are three commonly used coordinate systems: Cartesian, cylindrical and spherical. In this chapter, we will describe a Cartesian coordinate system and a cylindrical coordinate system.
 

Is there a universal coordinate system?

The UTM (Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide. UTM zones are numbered consecutively beginning with Zone 1, which includes the westernmost point of Alaska, and progress eastward to Zone 19, which includes Maine.

Why are my coordinates wrong in ArcGIS?

Cause. In some cases, the XY points display in the wrong location if a projected coordinate system is used instead of a geographic coordinate system. The XY points are in decimal degrees, but the projected coordinate system attempts to display the points as units of feet instead of as decimal degrees.

What kind of coordinate systems are used in mapping?

Two basic types of coordinate systems exist for geographic data: geodetic coordinate systems based on map projections and geographic coordinate systems based on latitude and longitude (for details, see for example Hake et al., 2002; Longley et al., 2006).

What is WGS84 coordinates?

The World Geodetic System 1984 (WGS84) is a datum featuring coordinates that change with time. WGS84 is defined and maintained by the United States National Geospatial-Intelligence Agency (NGA). It is consistent, to about 1cm, with the International Terrestrial Reference Frame (ITRF).
