The invention relates to the technical field of surveying and mapping remote sensing, in particular to an automatic tool for temperature vegetation drought index production and thematic map making, which comprises a data preprocessing module for image acquisition and preprocessing of surface temperature data and vegetation index data; a data calculation module used for calculating temperature vegetation drought grade data; a thematic map making module used for automatic production of drought grade thematic maps; the automatic production method specifically comprises the following steps: configuring a drawing template for drought grade grading result data, and controlling to generate a thematic map. The embodiment of the invention provides an automatic tool for temperature vegetation drought index production and thematic map making. By obtaining surface temperature data and vegetation index data, automatically fitting temperature vegetation index model calculation coefficients of all regions, calculating tempe
