Techniques for injecting a vehicle into a high speed transportation system are described. A travel request is received from a user. The user is determined to be authorized to travel using the high speed transportation system, based on a profile associated with the user. An injection portal for the user to enter the transportation system is identified. One or more instructions for the user are provided, relating to the injection portal. A vehicle associated with the user is identified at the injection portal. Characteristics of the vehicle are sensed at the injection portal, including a center of gravity of the vehicle. The characteristics are determined to satisfy threshold values, and the vehicle is authorized for travel in the transportation system. A vehicle profile is generated. The vehicle profile is transmitted to a second controller associated with the transportation system. The vehicle is injected into the transportation system.

Systems and methods for indexing geological features are disclosed. In one embodiment, a method for indexing geological features includes accessing a database storing a plurality of map objects that originate from documents. Each map object includes a map defined by a geographical boundary and a text caption. The method includes, for each map object, determining a plurality of geohashes within the geographical boundary, and includes, for each map object, comparing terms of the text caption with a list of geological keywords. For each map object, the method includes identifying one or more geological noun phrases within the text caption that match one or more geological noun phrases of the list. The method includes determining, for each geological noun phrase, one or more geohashes associated with the geological noun phrase and, for each geohash, determining a frequency that the geohash is associated with the geological noun phrase.

Systems and methods for normalizing and searching electronic data, such as chemical material property data, are disclosed. In one embodiment, a method includes receiving electronic data from a source. The electronic data is formatted in a source format. The method further includes converting the source data into a normalized format, and storing normalized electronic data in levels of a nested model. The method further includes receiving a search or browse query directed toward normalized properties in a first level of the nested model or a second level of the nested model, in any non-hierarchical order. The method also includes searching the nested model and causing for display on an electronic display one or more entities satisfying the query and maintaining the integrity of all parameters of the query across all selected properties queried in any non-hierarchical order.
