Sensor data may be generated regarding movement in one or more planes and used as boundaries for the field of view. A geographic location may also be associated with the field of view. Fields of view from two or more geographic locations may be aggregated to determine a collective field of view. The collective field of view may be provided to an electronic display. In some cases, the field of view may be a field of fire associated with a ballistic weapon. ## Claims ### Claim 1 A method of determining a field of view, comprising: receiving sensor data regarding a field of view, the sensor data comprising measurements indicative of one or more boundaries for the field of view; determining a geographic location at which the sensor data was generated; analyzing the sensor data and the geographic location to determine the field of view; aggregating fields of view from two or more geographic locations into a collective field of view; providing the collective field of view to an electronic display, the collective field of view is a collective field of fire for two or more weapons; and generating an alert based in part on whether a geographic location associated with a first field of fire is located within a second field of fire. ### Claim 2 (depends on 1) The method of claim 1, wherein the one or more boundaries for the field of view comprise azimuth measurements within a first plane. ### Claim 3 (depends on 2) The method of claim 2, wherein the one or more boundaries for the field of view comprise tilt measurements within a second plane. ### Claim 4 (depends on 1) The method of claim 1, wherein the geographic location is determined using a satellite-based positioning system. ### Claim 5 (depends on 1) The method of claim 1, wherein the one or more boundaries for the field of view comprise range measurements from a range sensor. ### Claim 6 (depends on 1) The method of claim 1, further comprising: associating the sensor data with a weapon; retrieving weapon data from a memory, the weapon data comprising range data and ballistics data for the weapon; and using the weapon data to determine the first field of fire or the second field of fire. ### Claim 7 A method of determining a collective field of view using sensor data, the method comprising: aggregating fields of view from two or more geographic locations into a collective field of view; providing the collective field of view to an electronic display, wherein the collective field of view is a collective field of fire for two or more weapons; and generating an alert based in part on whether a geographic location associated with a first field of fire is located within a second field of fire. ### Claim 8 (depends on 7) The method of claim 7, wherein one or more boundaries for each field of view comprise azimuth measurements within a first plane. ### Claim 9 (depends on 8) The method of claim 8, wherein the one or more boundaries for each field of view comprise tilt measurements within a second plane. ### Claim 10 (depends on 9) The method of claim 9, wherein the geographic location is determined using a satellite-based positioning system. ### Claim 11 (depends on 10) The method of claim 10, wherein the one or more boundaries for each field of view comprise range measurements from a range sensor. ### Claim 12 (depends on 7) The method of claim 7, wherein the alert is provided to a mobile device at the geographic location. ### Claim 13 (depends on 7) The method of claim 7, wherein, the alert is provided to a mobile device associated with the second field of fire. ### Claim 14 A method, comprising: using sensor data to determine at least two fields of view; aggregating the fields of view into a collective field of view; providing the collective field of view to an electronic display, wherein the collective field of view is a collective field of fire for two or more weapons; and generating an alert based in part on whether a geographic location associated with a first field of fire is located within a second field of fire. ### Claim 15 (depends on 14) The method of claim 14, wherein one or more boundaries for each field of view comprise azimuth measurements within a first plane. ### Claim 16 (depends on 14) The method of claim 14, wherein one or more boundaries for each field of view comprise tilt measurements within a second plane. ### Claim 17 (depends on 14) The method of claim 14, wherein the geographic location is determined using a satellite-based positioning system. ### Claim 18 (depends on 14) The method of claim 14, wherein one or more boundaries for each field of view comprise range measurements from a range sensor. ### Claim 19 (depends on 14) The method of claim 14, wherein the alert is provided to a mobile device in the second field of fire. ### Claim 20 (depends on 14) The method of claim 14, wherein the alert is an audio alert.
