Quick Search
- -The quick search help feature assist users in performing a valid search. Each search is unique based on query type. Users can query quick search by Address, Lat/Long or Place Name.
- -Search by Address example:
50 W. Washington St
Search by Lat and Long example:
41.8270, -87.6423
Search by Place Name example:
Daley Center
Additionally, data sets that contain zip codes can be searched using the dataset ID (all lowercase) and zip code. The dataset ID is the data set name with “_” instead of spaces. Below are examples:
Business Licenses 60601:
business_licenses 60601
Pot Holes Reported in 60602:
311_service_requests_pot_holes_reported 60602
The search results for the above type of search will appear as points on the map. Quick search results will also be displayed in the grid section as rows of data. In general, any type of query whether performed via Quick search or Advanced Search will display on both the map and the grid.
- -Advanced Search
-Advanced Search allows you to combine search terms by setting specific parameters for your results.It gives the user the ability to narrow their searches by a series of different filters such as adding additional rules, groups,datasets and Geo spatial-filters.
-Selecting data and date range
-To query by data and date range...Click on add datasets, select the saved dataset from the list (for ex: business license); click submit. Add a rule or group to your dataset (Adding a rule or group gives the user an option to query by date, city, name, address, etc. depending on the search criteria.)
Date range can be specified with the parameters of:
-
-
- equal -
- not equal -
- less -
- less or equal -
- greater -
- greater or equal -
- between
Search around a parameter (Point)
-To search with given point or boundaries the Geo spatial-filters will have to be applied. There are two filters to search by “Within” and “Near”. “Within” is used to search boundaries within a query. “Near” is used to search within a given parameter or around the area of your local.
-Within have search boundaries of:
--
-
- Map Extentu -
- Drawn Extent (create polygon or rectangular perimeter) -
- Citywide (within the city limits) -
- Zip Code (within a given zip code) -
- Ward (within a given ward) -
Near have search points of:
--
-
- Near “Me” (search around the user geo location) -
- Near “Marker” (search around a given area) -
Table Functions

-Measure Distance and Area
-Measuring distances and areas is a function within OpenGrid that allows the user to perform measurements between any given point to another. Once the measurement tool is selected the user will be prompt to start creating measurements by adding points on the map.
-Measurement and Tools
-Click the measurement tool icon.
-
- A measurement tool textbox will appear with an option to create a new measurement.
- -
-
