High-resolution image data management system (1 m, mainly tiff, refer to others)

Image Management System

[System construction background]
So far, the image storage problem of massive data has not been well solved. Most of the software is not difficult to adjust images, and image separation is serious, that is, the software supports a small number of image formats and has weak functions. The traditional image compression technology is insufficient in terms of compression ratio, restoration speed, and massive image management, this severely hinders the promotion and use of high-resolution remote sensing data. In response to the above problems, our company developed an image management system.
[Main functions]
1. Image File Management
In the "Image File" menu, you can click "Open Data Source", "Close data source", "add image", "delete image", "recreate spatial index", "Image Compression", and" transfers CAD files, transfers CAD files, and other operations to manage the warehouse inventory system.

2. Query
The image management system supports multiple query methods, including file name query, place name query, and interactive query.

3. Adjust and unload Graphs
Image processing provides multiple methods for unloading images: based on the map, Place Name, coordinate, point, line, and area.

4. Editing
The editing function allows you to add, delete, and change drawing elements in a timely manner.

5. analysis and statistics
This function can be used to collect the area, perimeter, edge length, vertex coordinates, and the number of images contained in the selected area (any shape, and can be previewed and printed in the Word document. This function can be used to measure the area, perimeter, and margins of buildings, residential areas, and planned land use, and provide an auxiliary basis for decision-making by relevant departments.

[System advantages]
1. Lossless Image Compression
2. Manage massive data
Because of the image compression technology, the amount of data used by the system is greatly reduced. Generally, the original data is reduced by 10 to 20 times without obvious data details loss.
3. Support for multiple file formats
Autocad dwg drawing files, DXF drawing interchange files, microstation dgn design files, commonly used image files TIFF, Image Positioning files crls or TFW. These commonly used image files can be output as image compression files or imported into related image file datasets.
4. fast operation
The system uses the image data compression technology to process the managed image data quickly. According to our tests, the data volume of about 300 normal images is stored in the TIFF format, which requires about 24 GB of data. It takes almost no time to open all images, after using the ECW compression technology, the image data volume is only 1 to 2 GB, and all data is transferred to the system. The time required will not exceed one minute.
