1. Preface

ArcGIS Runtiem with share as, available from the ArcGIS desktop The content tool often occurs when exporting. geodatabase files, such as a data table with more than 4w of data, but when exported to Geodatabase, it is sometimes found that the data is only 1w and data is lost. Why was it lost? Before also did not delve into such a problem, is not very clear the exact point of the problem where, is simply know the current viewable area to cover all maps, you can export all the data, presumably guessing is the problem of the visible area. Today, for this piece of careful study, do a simple summary.

2. Problem study export in ArcMap. Vector data in geodatabase format in general there are two ways to do this: (as if there were Python script generation specifically not studied)

• method One : Use file--Share as->arcgis Runtime content Export

• mode two : Use the toolboxes, Data Management Tools->package, Create Runtime Content in the Toolbox

What is the difference between these two ways?

Mode one: The export range is implicitly considered the current viewable area. Mode two: The export range defaults to full-scale, can be selected according to the extent range.

For the way one author has done the following tests:

The map document (. mxd) is saved by enlarging the map to Figure 2, as shown in the full extent 1 above. Then open the file--Share as->arcgis Runtime content tool, in the pop-up window, the ArcGIS Runtime Content tab sets the path to the files storage, Feature and tabular Data tab, set the Export all data option in the settings (export all). After the export is complete, we get a file with a suffix of. Geodatabase. The file can be exported to filegdb using the copy Runtime geodatabase to file Geodatabase tool in the toolbox, and the results are overlaid with the original results by 3. This also explains why we use the way a data export often has a missing data situation. The reason is that the current viewable area is limited.

For mode two, the setup process is simple to follow the instructions, and one of the parameters to be aware of is the extent range parameter, which specifies the range to select or crop the feature.

• default--Default-The range is set based on the maximum range of all participating layers. This is the default setting.
• Union of inputs--Input-the maximum range of all inputs.
• Insersection of input--Input-the minimum range that all inputs share.
• As Specified below--as specified below-Specifies the minimum and maximum range values.
• The same as display--is the same as the display-the range equals the data frame or visible display range.

3. Summary of issues

mode one : Use the file-and Share as->arcgis Runtime content to export features within the current viewable area.

method Two : Use the toolboxes, Data Management Tools->package, Create Runtime content in the toolbox to export all features by default, Specifically, you can have more extent range attribute control.
