This option is used in ArcMap when we get data that started off as a CAD dataset, and someone (else) "guessed" at what the projection was, and they were clearly wrong, but we have no idea what the CAD was origi
The project-on-the-fly functionality in ArcMap is very good for quickly viewing data in different coordinate systems. The exercise below will demonstrate the properties of various map projections and their effect on the data displayed in ArcMap. Start ArcMap with a new, empty map. Depending on...
您可以指定 ArcScene 在任意一个 ArcGIS 支持的预定义地理坐标系或投影坐标系中显示数据。通常情况下,此设置将与至少一个图层源数据坐标相匹配。 右键单击内容列表中的场景图层,然后单击场景属性。 单击坐标系选项卡。 双击预定义。 浏览文件夹以找到所需坐标系,然后单击该坐标系。
Instructions provided describe the steps to convert AutoCAD DWG files to a GIS-compatible file geodatabase. Note: ArcMap is in Mature support and will be retired March 1, 2026. There are no plans for future releases of ArcMap, and it is recommended that you migrate to ArcGIS Pro. See Mi...
Y-axis coordinate (X, Y)—A point on the positive y-axis from the origin point used to orient the fishnet. Cell size (Width, Height)—The size of the cells in the x and y directions. Cell sizes are expressed in coverage units and should reflect the map projection of the coverage. ...

The world file does not contain any information about the intended spatial reference system. You still need to Define Projection (presumably WGS 1984), in addition to using the world file. It works just fine for me, with your original world file. Because the data ...
