Hypermap import ArcGIS data file

1. Download

Download SuperMap iDesktop 10i desktop tool from SuperMap official website

Official download page

2. Establish working space and spatial database

Spatial database can use MySQL external database or file database.
When creating a database in an existing MySQL instance, please select the utf8 format to prevent the import of Chinese characters in the ArcGIS data file from failing!

Three, import ArcGIS vector data

Hypergraph data import

When importing ArcGIS vector data using SuperMap iDesktop, you only need to select shp, and the tool will automatically associate files with the same name according to the file name (so the file names of dbf, shp, and shx must be consistent).

Steps: Start-Data Import-arcgis

Shapefile file extensions

shp—The main file that stores the feature geometry. Required.

.shx—The index file that stores the index of the feature geometry. Required.

.dbf—The dBASE table that stores the attribute information of features. Required.
There is a one-to-one relationship between geometry and attributes, which is based on record number. Attribute records in the dBASE file must be in the same order as records in the main file.

.sbn and .sbx—The files that store the spatial index of the features.

.fbn and .fbx—The files that store the spatial index of the features for shapefiles that are read-only.

.ain and .aih—The files that store the attribute index of the active fields in a table or a theme’s attribute table.

.atx—An .atx file is created for each shapefile or dBASE attribute index created in ArcCatalog. ArcView GIS 3.x attribute indexes for shapefiles and dBASE files are not used by ArcGIS. A new attribute indexing model has been developed for shapefiles and dBASE files.

.ixs—Geocoding index for read-write shapefiles.

.mxs—Geocoding index for read-write shapefiles (ODB format).

.prj—The file that stores the coordinate system information. Used by ArcGIS.

.xml—Metadata for ArcGIS—stores information about the shapefile.

Chinese explanation:

The shapefile is a data type that has no topological relationship in vector data.
It contains at least 3 files, dbf, shp, shx.
Among them: dbf file stores the attribute information of vector data;

shp stores the spatial information of vector data.
shx is an index file that retains the geometric characteristics of the features.
In addition, the shapefile can also include other files, such as sbn, sbx, prj, etc.
sbn and sbx are also spatial index files, and .prj is a projection file of data.

Among them, three of .shp, .shx, and .dbf cannot be deleted. If one is deleted, an error occurs. The shp is gone, everything is gone, just as the so-called skin does not exist, Mao will be attached. Although deleting shx can't open the file, there are tools to repair it. It can also be repaired by deleting the .dbf file, but the attributes cannot be retrieved. Deleting the .prj file will result in loss of projection information. After the .sbn and .sbx files are deleted, the index created will be lost, but it does not affect the overall situation.

Fourth, import ArcGIS data image

Steps: Start-Data Import-Image Bitmap
When processing images with ArcGIS, you must first convert images in TIFF format into IMG format images. After the image conversion is completed, four format files are generally generated: .ige, .img, .rde, .rrd. As shown in the figure:
Example
Among them, img is the image format, and ige is the data file. Three files are automatically generated. When the image data is larger than 2G, arcmap generates img, ige and rrd files. The
img file becomes the index file, the
rrd file is the pyramid file, and the
ige is actually used to store the raster data.
rde file: In some cases, the pyramid file ( rrd ) will also exceed 2GB, and then an rde file will be created to store this information.
