HIST-DPW Software images are often used to produce large-scale maps.\u00a0 Recently, with the development of high-resolution satellite images, businesses using satellite images to produce high-resolution maps are increasing.<\/p>\n
Recently, a project to produce a digital topographic map using satellite images with a spatial resolution of less than 1 m above the ground has been actively carried out.<\/p>\n
For aerial images, sensor modeling is performed using collinear conditional expressions, but for satellite images, various sensor modeling is applied depending on the type of image. Therefore, in order to perform stereo stereoscopic vision using satellite images, accurate sensor modeling for satellites is required.<\/p>\n
In Korea, a numerical photogrammetry system that can cope with foreign equipment has not yet been developed.<\/p>\n
Therefore, in this study, trajectory modeling was performed on the SPOT-5 stereoscopic image, and the accuracy was verified in stereoscopic vision by mounting it in a numerical photogrammetry system.<\/p>\n
As a result, SPOT-5 stereo stereoscopic vision without parallax was generated through the sensor model, and it was found that 1\/25,000 numerical topographic maps could be produced.<\/p>\n
Domestic geospatial information solutions (GIS) are making great strides forward one after another, outpacing foreign competitors in the public and private markets.<\/p>\n
According to the industry on the 14th, \u2018Intramap\u2019, a GIS engine localized by Korea Spatial Information and Communication (CEO Kim In-Hyeon), was selected as the basic GIS engine for the 2nd pilot project of \u2018Building a National Geospatial Information Integration System Infrastructure System\u2019 recently ordered by the Ministry of Land, Transport and Maritime Affairs. .<\/p>\n
It is the second time that a domestic GIS engine has been adopted for a large-scale public GIS construction project after the new address guidance system ordered by the Ministry of Public Administration and Security in 2005. Korea Geospatial Information and Communication has also supplied an \u2018intramap\u2019 to the new address guidance system.<\/p>\n
In particular, the national geospatial data integration system construction project will start from next year to 2012 with a total of 400 billion won, and it is expected that the domestic market share of domestic GIS engines will increase rapidly.<\/p>\n
president of Korea Spatial Information Communication, said, \u201cA domestic GIS engine with high technical difficulty was already developed in the early 2000s, but the domestic market share is still only 20%. Domestic production is expected to overtake foreign production within three years,\u201d he said.<\/p>\n
In the early 2000s, the domestic frenzy is also strong in the market for \u2018Suchidohwagi\u2019, which was swept away by foreign producers.<\/p>\n
