Abstract

The paper presents a methodology to produce forest parameters and tree instances to large area 3D maps or city models from satellite images.
The process flow includes the calibration of the satellite image, the forest parameter estimation, the generation of tree instances from the forest parameters, and the integration of the tree instances to D city model and visualisation.
Due to the calibration, forest parameter models developed for other areas can be used in the estimation. SPOT satellite images were used to generate tree instances to a Finnish 3D city model. The number of trees/ha, the mean diameter/ha, the stem volume/ha, and the tree type (coniferous or deciduous) were estimated to each pixel of the SPOT image.
Tree instances based on these parameters were entered to D visualisation software with the state of art city model. The results show, on one hand, the discrepancies between the 10 meter satellite image and the aerial image, like some trees on the roof or in the street.
On the other hand, it shows the high geometric quality of the SPOT satellite image and its suitability to the production of tree instances to standard city model
