Resource selection surface ASCIIs

Resource selection surfaces (both the predicted surfaces and the exponentiated surfaces) used with ResistanceGA to optimize landscape resistance surfaces for eastern indigo snakes in Bauder et al. Please refer to our paper for the details of the Level II, Level III, and SRSF surfaces.本数据集所用的资源选择表面（Resource selection surfaces）包含预测表面与指数化表面两类，该类表面配合ResistanceGA工具，用于优化鲍德尔等（Bauder et al.）针对东部靛蓝蛇的研究中的景观阻力表面。有关二级（Level II）、三级（Level III）及SRSF表面（SRSF surfaces）的详细信息，请参阅本文。
