Mapping tree crown is critical for estimating the functional and spatial distribution of ecosystem services. However, accurate up-to-date urban mapping remains a challenge due to time-consuming nature field sampling heterogeneity. Another data cost, which always concern low-cost processing forest maps on large scales. Here, we developed novel working framework by integrating an advanced deep learning technology, Mask Region-based Convolutional Neural Network (Mask R-CNN) model with Google Earth images detect cover in New York's Central Park, typical testbed area highly heterogeneous cover. The results indicated that number detection rate estimated R-CNN was 82.8% 81.8% entire study area. detected isolated trees closed areas recall 87.5% 81.6% numbers, respectively. analysis indicates could accurately crowns under complex environments demonstrates great potential map covers.

Forests can be efficiently monitored by automatic semantic segmentation of trees using satellite and/or aerial images. Still, several challenges make the problem difficult, including varying spectral signature different trees, lack sufficient labelled data, and geometrical occlusions. In this paper, we address tree multispectral imagery. While carry out large-scale experiments on deep learning architectures various input combinations, also attempt to explore whether hand-crafted vegetation indices improve performance models in trees. Our include benchmarking a variety remote sensing image sets, architectures, bands as inputs, number indices. From our experiments, draw useful conclusions. One particularly important conclusion is that, with no additional computation burden, combining categories indices, such NVDI, ARVI, SAVI, within single three-channel input, state-of-the-art accuracy improved under certain conditions, compared high-resolution visible nearinfrared input.
