Data normalization of aerial images

A system configured for analysis of aerial images, comprising a data-processing system, the data-processing system comprising at least one processor and at least one memory, the processor and/or the memory being configured to realize a data-processing storage component, a segmentation component, a projection component and an error minimizing component,

• wherein the data-processing storage component is configured for providing at least two input orthophoto maps and at least two input digital elevation models relating to an area, wherein each orthophoto map provides an orthogonal visualization of an area that allows to measure true distances and wherein the at least two input orthophoto maps and/or the at least two input digital elevation models relate to the same area at different points in time,
• wherein the segmentation component is configured for generating at least one or a plurality of polygon(s) for the at least two orthophoto maps relating to the area, each polygon approximating a part of the corresponding input orthophoto map,
• wherein the segmentation component is configured for generating the polygon(s) based on the at least two input orthophoto maps,
• wherein the segmentation component is configured for assigning different classes to different portions of the at least two orthophoto maps,
• wherein the segmentation component is configured for assigning portions comprising same classes to groups,
• wherein the segmentation component is further configured for determining the polygon(s) based on the determined groups, and
• wherein the error minimizing component is configured for minimizing positional errors on at least one or a plurality of parts of the at least two orthophoto maps.
