You can search for points of interest, such as businesses and facilities, using data from Data Axle, SafeGraph, and other POI data sources. For example, you can search for hospitals or search using the name of a specific hospital. You can also search within a category or industry or search using NAICS or SIC codes.

The points of interest (POI) search workflow has four stages: search, refine results, set the map style, and explore the results. To search for points of interest, do the following:

  1. On the Maps tab, click Create maps and select Points of interest (POI) search.

    The Points of interest (POI) search pane appears.

    Tip:

    You can also launch this workflow using the search tool.

  2. In the Geography section, use the Analysis extent drop-down menu to define the geographic extent of the analysis by searching for a standard geography, selecting Current map extent, or choosing a site.

    Selecting a standard geography or site locks the analysis extent to that area. If the geography is set to Current map extent, you can click Refresh search Refresh as you pan and zoom the map to perform your search on a new extent.

    Note:

    You can modify the analysis extent at any time in the Geography section.

  3. If the country or region is set to a location with multiple POI data sources, use the Data source drop-down menu to select the data source. You can set the default POI data source in the app preferences.
  4. Click the Enter category, keyword, etc. field and do any of the following:
    • Click the Keyword tab Keyword and enter your search terms in the Enter name or category field. For example, you can search for theme parks or search using the name of a specific theme park. Optionally, use the Include related points toggle button to enable a semantic search, returning variables related to the search terms you entered.
    • Click the Category tab Category and enter your search terms in the Enter category name field or select from a list of categories included with the selected POI data source. For example, you could browse to and select Farming, Forestry, Pets & Animals > Veterinary Services.
    • Click the Code tab Code and enter your search terms in the Enter name or code field or select from a list of industrial classification codes. Click the Classification system drop-down menu to change the industrial classification code used. For example, if you are using Data Axle as the POI data source, you can search for schools or enter the Primary NAICS code 61111007. Or, try using number + *, such as entering 72* to search for Accommodation and Food Services.
    • Click the All points tab All POIs and click Add all points to map all points of interest (up to 5,000) within the search extent for the selected country. Data providers restrict the number of points returned in a search to 5,000. To refine your results, try either reducing the size of your analysis or using advanced search conditions.
    • Click the Advanced search tab Advanced search to create an advanced POI search using conditions. To learn more about prefiltering your search, see the Add conditions section below.
    • Click the Saved searches tab Save to use a previously saved search.
  5. Optionally, click Save search. Name your search and click Save.
  6. To perform the search, click Search.

    The search results appear on the map and Results pane.

  7. In the Filters section, refine your results. Click Show filters and do any of the following:
    • To search within the results by keyword, enter text in the search field.
    • To show only search results using specific attributes, expand the attribute's section and either use the check boxes or search within the attribute to narrow the results. For example, if you expand the City section and select Riverside and Redlands, only the results from those two cities are included.
    • If you are using Data Axle as the POI data source, you can adjust the slider handles for the numeric attributes to define the minimum and maximum values included in the analysis, or enter the values manually.

    • Optionally, click Reset all to clear your filter selections or, if you've selected all items in an attribute section, click Unselect all at the bottom of the section. You can also remove filters individually by clicking Remove Remove on a filter in the workflow pane.

    The map automatically updates to show the filtered search results.

  8. In the Style section, do the following:
    1. Use the Map style drop-down menu to choose a style. The default style is Location (single symbol). For more information, see the Map styles section below.
    2. Click Show style options and do any of the following, depending on the map style chosen:
      • Use the Cluster points toggle button to aggregate points into clusters or display them individually on the map.
      • Use the Symbol drop-down menu to select a symbol to represent points of interest on the map.
      • Use the Fill color drop-down menu to select the symbol's fill color.
      • Adjust the Size slider to change the size of the symbol or enter a value manually.

    The map automatically updates to show the selected style. Map style information appears in the Legend section.

  9. If you change the map extent during the workflow, click the Search this area button on the map to refresh the analysis extent of the search.
  10. In the Results pane, explore the POI search results as a summary, histogram, bubble chart, and table.

    See the Explore the results section below for more information.

    Note:

    The results pane shows a histogram and bubble chart only when using Data Axle as the data source.

  11. Optionally, click Clear all to clear your search and results.
  12. Click Save layer.

    Enter a name for the layer and click Save. The saved layer can be accessed in the project pane in the Points of interest (POI) layers section.

    • Use the Rows per page drop-down menu to change the number of rows displayed in the table. Click Next Next or Back Back to navigate the table pages.

Map styles

You can style the points on the map using different map styles. Depending on the data source, the following styles are available:

Location (single symbol)

Display data on a map with a single symbol to show the distribution and reveal patterns. For example, when mapping a list of coffee shop locations, you may see coffee shops clustered together in a business district. Use the Cluster points check box to turn clustering on or off. To change the symbol, modify its color and size, or upload your own, use the Symbol drop-down menu.

Place

Use intuitive iconography to visually identify what kinds of places the points of interest represent. For example, the Place map style represents parks with tree icons, grocery store with a shopping cart icon, and restaurants with a knife and fork icon. The icons are curated and match the datasets available.

Counts and amounts (color)

Map numeric information by color to highlight data variances. For example, a light-to-dark color theme can show low-to-high data values. Click More options to choose a style for the symbols, change the attribute being mapped, and adjust the graph. Check the Classify data check box to adjust the classification method and breaks.

Counts and amounts (size)

Use an orderable sequence of proportional sizes to represent numerical data or ranked categories. Larger symbols indicate larger numbers. Click More options to choose a style for the symbols, change the attribute being mapped, and adjust the graph and clusters. Use the Size sliders to adjust the relative size of the symbols. Check the Classify data check box to adjust the classification method and breaks.

Type (unique symbols)

Use unique symbols to show different types of things rather than numerical counts. For example, use different colors to represent restaurant cuisine types. It is recommended that your layer show fewer than 10 types, as more types become difficult to distinguish. By default, the 10 most common types are shown, and additional types are grouped together in an Others group. Click More options to choose a style for the symbols and set the color ramp, change the attribute, or edit the symbols individually. Use the Cluster points check box to turn clustering on or off.

Heat map

Map the location of a large number of point features that are close together and aren't easily distinguishable. Heat maps use the points in a layer to calculate and display the relative density of points on the map as colors ranging from cool (low density of points) to hot (many points). Best practice is to avoid heat maps if there are only a few points; instead, map the individual points. Click More options to adjust the color gradient. Use the Area of influence slider to adjust the clusters. Using the Select tool, you can select heat map polygons or select underlying point data to create rings, drive times, or walk times.

Color & Size

Map two attributes in your data and finalize the color and size of point symbols on the map. You can use the same attribute twice: first to set the size of the symbols and again to set the colors, based on the part of the data you want to emphasize. This is suitable when you want to show count information, such as total population, shaded by a variable, such as population density.

Types & Size

Use unique symbols to show different types of things, with the size of the symbol representing a count. For example, use different colors to represent restaurant chains, and use different sizes to represent the number of employees. It is recommended that your layer show fewer than 10 types; more types become difficult to distinguish. By default, the 10 most common types are shown, and additional types are grouped together in an Others category. Click More options to choose a style for the symbols, change the attributes being mapped, or edit the symbols individually.

Add advanced search conditions

An advanced search condition is a rule that prefilters your search results. This prefiltering provides more specificity to the search query since the results must match at least one of the criteria. Since the number of points returned in a search is restricted to 5,000, it is useful to prefilter the search for refined results. In an advanced search, select a field to condition then choose a filter operator and set a value.

For example, you can add an advanced search condition in your point of interest (POI) search to only show businesses with more than 20 employees. Create a condition as follows:

  • For field, choose Employee Count.
  • For the filter operator, choose is greater than.
  • For value, enter 20.

Multiple conditions can be used in a search to further prefilter the results. For example, create an additional condition as follows:

  • For field, choose State Abbreviation.
  • For the filter operator, choose contains.
  • For value, enter PA.

To link multiple conditions, use a logical operator to select whether all conditions or any of the conditions must be met. The logical operator for all conditions to be true is represented by AND. Choosing all conditions means that the results must match each conditioned criterion. The logical operator for any conditions to be true is represented by OR. Choosing any conditions means that the results must match at least one of the conditioned criteria.

Add conditions

To add conditions to a points of interest (POI) search, do the following:

  1. In the Points of interest (POI) search pane, click the Enter keyword, category, etc. field and click the Advanced search tab Advanced search.
  2. Click + Add condition.
  3. Select a field to prefilter from the drop-down menu.
  4. Choose a filter operator from the drop-down menu.

    There are different filter operators depending on the selected data source, the type of search (keyword, category, or code), and whether the field for prefiltering is text or numeric.

  5. Enter a value.
  6. Optionally, repeat the previous steps to create additional conditions.
  7. If you are using more than one condition, set the logical operator. Choose either All of the following are true or Any of the following are true.
  8. Click the Options button Options and do either of the following:
    • Click Delete to delete the condition.
    • Click Add to condition group to create a condition group.
  9. To reset your conditions, click Clear All.
  10. Optionally, to save the advanced search, click Save search. Name the search and click Save.
  11. To apply the advanced search, click Search.

Use condition groups

To create a more complex advanced search, use condition groups. Each condition group uses its own logical operator. Some condition groups may require that all of the conditions are true and others may require that any of the conditions are true. Furthermore, each condition group is logically related to one another. Either all condition groups are required to be true or any of the condition groups are required to be true.

  1. Click the Options button Options for a condition.
  2. Click Add to condition group.

    A new group containing the existing condition and an empty condition appears.

  3. Select a field, choose a filter operator, and enter a value for the empty condition.
  4. To add conditions to the group, click the Options button Options and click Add to condition group.
  5. Use the logical operator drop-down menu to choose either All of the following are true or Any of the following are true.
  6. Optionally, repeat the previous steps to create additional condition groups.
