Abstract: A method of presenting weather data, representing weather events, on a graphical user interface (GUI). The weather data is received. At least one of the weather events is present in at least one of several altitude zones for a physical area centered on a reference point. A corresponding intensity rank is assigned to each of the weather events. Each of the altitude zones is divided into a corresponding grid defined for the physical area. Each corresponding grid has corresponding sectors defined by corresponding lines and vertices. A corresponding highest intensity ranking weather event extant in the corresponding sectors is assigned to each of the corresponding sectors in the altitude zones. A selection of a selected altitude zone is received from among the altitude zones. A rendered image is generated by rendering the corresponding grid for the selected altitude zone. The rendered image is displayed on the GUI.

Abstract: A method including receiving a spatial query on spatial data. The spatial query has a spatial query extent including a sub-portion of the spatial data. A projection type is selected for the spatial query. A framebuffer is created for the selected projection type. Vertex buffers are established to hold a geometry of the selected projection type. The vertex buffers are passed from a CPU to a GPU. A spatial geometry of the spatial query extent is rendered into the framebuffer by projecting feature vertex data for features that fall at least partly within the spatial query extent into the vertex buffers. Rendering generates rendered framebuffer pixel values. Pixel values of the rendered framebuffer are retrieved as bytes on the CPU. A spatial query result is processed that includes or uses the pixel values.

Abstract: Systems and methods for assessing and presenting aviation-focused weather information are provided. One computer-implemented method comprises receiving, at one or more processors, weather information for a select geographic location and a select time period, the select time period comprising a plurality of consecutive hours, and the weather information including general weather conditions and aviation-specific weather conditions for each of the hours; and displaying, on a display unit of an electronic device, a weather forecast user interface configured to present the weather information, wherein the weather forecast user interface comprises a first region configured to depict one or more of the aviation-specific weather conditions for each hour of the select time period using color-coding or shading associated with the corresponding aviation-specific weather condition.
