A computer-implemented method of preprocessing images for efficient image data transmission to a user interface configured to display the preprocessed image, the method comprising: accessing an image ; accessing information indicating locations of a plurality of features of interest within the image ; determining a first tile arrangement indicating a first quantity of tiles associated with a first zoom level, each of the first tiles including a portion of the image at a first downsampling level corresponding to a first level of detail of the plurality of features of interest within the image at the first zoom level such that the first tiles collectively represent the image ; determining one or more tiles associated with the portion of the image ; generating the determined one or more tiles; transmitting only the generated one or more tiles of the first tile arrangement to a user interface for display ; displaying a feature type analysis indicator comprising a histogram showing a graphical distribution of quantitative values associated with one or more of the plurality of features of interest; receiving, via user selection of a feature type selector , a feature type associated with the one or more of the plurality of features of interest; displaying, in response to the user selection of the feature type selector, an updated histogram showing the graphical distribution of quantitative values associated with one or more of the plurality of features of interest corresponding to the selected feature type; receiving a selection of a portion of the updated histogram to fine-tune a threshold parameter associated with the one or more of the plurality of features of interest corresponding to the selected feature type ; and updating the user interface to display features of interest satisfying the fine-tuned threshold parameter within the displayed one or more tiles. accessing an image ; accessing information indicating locations of a plurality of features of interest within the image ; determining a first tile arrangement indicating a first quantity of tiles associated with a first zoom level, each of the first tiles including a portion of the image at a first downsampling level corresponding to a first level of detail of the plurality of features of interest within the image at the first zoom level such that the first tiles collectively represent the image ; determining one or more tiles associated with the portion of the image ; generating the determined one or more tiles; transmitting only the generated one or more tiles of the first tile arrangement to a user interface for display ; displaying a feature type analysis indicator comprising a histogram showing a graphical distribution of quantitative values associated with one or more of the plurality of features of interest; receiving, via user selection of a feature type selector , a feature type associated with the one or more of the plurality of features of interest; displaying, in response to the user selection of the feature type selector, an updated histogram showing the graphical distribution of quantitative values associated with one or more of the plurality of features of interest corresponding to the selected feature type; receiving a selection of a portion of the updated histogram to fine-tune a threshold parameter associated with the one or more of the plurality of features of interest corresponding to the selected feature type ; and updating the user interface to display features of interest satisfying the fine-tuned threshold parameter within the displayed one or more tiles. <EOS>
