Problems solved by technology

However, the biggest disadvantage of software developed in SDE mode is that the efficiency is too low. The processing efficiency of large data volume in SDE is much slower than that in mdb mode, and it is not as efficient as gdb.
This method is also impractical
[0007] In addition, ArcGIS data can also support data p

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0039] Example. A development method of an ArcGIS data processing tool, the process is as follows figure 1 shown, follow the steps below:

[0040] ① Pre-processing;

[0041] ② Establish a connection to the source database in a new thread; use the new thread to reconnect to avoid com errors called by the database space IWorkspace in subsequent operations;

[0042] ③Create the auxiliary library mdb in the new thread; using the conventional method, the creation of the auxiliary library mdb can create an empty one, or copy an mdb template to make the auxiliary library by means of file operations;

[0043] ④ Create the target library gdb in the new thread;

[0044] ⑤ Import data from the source database to the target database gdb;

[0045] ⑥ Perform graphic processing on the data in the target datab...

Abstract

The invention discloses a development method of an ArcGIS data processing tool. The development method comprises the following steps that 1, processing before operation is performed; 2, a source database connection is established within a new thread; 3, an auxiliary library mdb is created within the new thread; 4, a target library gdb is created within the new thread; 5, data is imported from a source database to the target library gdb; 6, graphic processing is conducted on data in the target library gdb according to a data processing requirement to form a result data graphic; 7, graphic data needing attribute processing is imported into the auxiliary library mdb for attribute processing and then is returned to the target library gdb after the attribute processing is completed; 8, operation errors produced in the processing process of the target library gdb and the auxiliary library mdb are collected in a generic array, progress log information in the processing process is displayed on interface and in log files through entrustment in a rolled mode; 9, a result library is generated, and the log files are output. The development method adopts the mode integrating the gdb and the mdb, accordingly improves the efficiency remarkably and can also improve user experience.

Description

technical field [0001] The invention relates to the field of ArcGIS development, in particular to a development method of an ArcGIS data processing tool. Background technique [0002] At present, the informatization work in various fields involves the processing of massive GIS data. ArcGIS is an international leader in the processing and application of GIS data. Generally, projects involving GIS data use ArcGIS as a platform. It is unrealistic to process the GIS data of some projects manually using the conventional ArcGIS platform, and some complex processing is difficult to do manually, which inevitably requires the development of some targeted GIS data processing software. [0003] The conventional way to develop GIS data processing software is to call the interface of ArcGIS, and use the COM component environment provided by it to process data. Because GIS data contains graphic information, the amount of data is generally very large, and the efficiency of software develo...
