The Making of Digital Orthophoto Map Based on INPHO

Applied Mechanics and Materials, 2011
INPHO is foreign professional digital photogrammetry software, including aerial triangulation encryption, digital terrain model matching, the digital orthophoto rectification and image mosaic series modules. This paper, taking DMC image as a case study, according to production practice, states the method of making Digital Orthophoto Map (DOM) using all

Geologic Mapping on Digital Orthophoto Quadrangle (DOQ) Images in Kansas

Transactions of the Kansas Academy of Science (1903-), 1995
Geologists usually map in the field on topographic quadrangle sheets or airphotos, and this information is transferred to a basemap in the office by a cartographer or research assistant. The geologist then has to check the map and make corrections (if necessary), and this procedure may occur several times depending on the accuracy of the copy [e.g ...

Greenhouse Detection Using Aerial Orthophoto and Digital Surface Model

2017
Detection of greenhouse areas from remote sensing imagery is important for rural planning, yield estimation and sustainable development. This study is focused on plastic and glass greenhouse detection and discrimination using true color orthophoto and Digital Surface Model (DSM).

A concept for topographic map updating using digital orthophotos

Photogrammetria, 1985
Abstract A method for topographic map updating is based on two digital orthophotos from digital aerial photographs. The first orthophoto corresponds to the old level of the map, the second contains, among others, the updating information. The working-steps begin with orthophoto computation and end with the generation of a screened groundplan of the ...

Picture histogram and interpretation of digital orthophotos in forest management

ISPA 2005. Proceedings of the 4th International Symposium on Image and Signal Processing and Analysis, 2005., 2005
The paper presents the possibilities of using histograms of a stand scene and visual interpretation of a digital orthophoto to estimate stand density and condition. Black-and-white aerial photographs with an approximate scale M ≈ 1:20, 000 and 60% overlap, obtained during cyclical survey of the Republic of Croatia, were used for this purpose ...

Accuracy analysis of digital orthophotos from very high resolution imagery

2004
The generation of digital Orthophotos now days can be done with aerial, but also very high resolution space imagery. For a real competition the geometric and radiometric quality has to be on the same level. Different QuickBird images have been used for the generation of orthophotos with 1m pixel size.

Digital Orthophoto as a tool for the restoration of monuments.

2000
For the restoration of monuments it is now becoming normal practice to carry out a preliminary study of the monument before starting any kind of work. The metric survey is one of the main operations required. For this reason, photogrammetry applications already have a large bibliography.

Using Iterative Orthophoto Refinements to correct Digital Elevation Models (DEM's)

1991
Abstract : A new technique is described that can be used to correct the digital elevation data obtained using digital correlation methods on terrain stereoimages. The new technique takes advantage of the speed of modern computers and the inherent geometric relationship between elevation data and orthophotographs to provide speedy, accurate and nearly ...
