Eco Devo - Eco Devo is an abbreviation for economic development. 

Edit Panel - When you open up edit-mode on a dashboard or a report in mySidewalk, the thing on the right side of your screen is the edit panel. When you add new visualizations, the edit panel changes to provide space for the edits to the visualization you are currently working on.

Effective Response Force - The set of vehicles / apparatus dispatched to incident within 60 seconds of when the call was answered in dispatch.

Equal Count - A data classification method that breaks up values based on the number of data points in the data set with an equal number of points in each bin. This method is often referred to as quantiles. An example of this method would be if you had 21 counties you were displaying divided into 3 bins you would have 7 data points displayed for each bin category, regardless of their distribution.

Equal Interval - A data classification method that divides a set of attribute values into groups that contain an equal range of values. For example, if you have 15 counties but a range from 1 to 81, your bins each have a range of 27 (1-26, 27-54, 55-81) and your counties could fall into any of the bins. There may be no counties with values in the range of 27-54 and only 2 counties from 55-81, but the data is classified to show this type of distribution. 

Geographic Harmonization - Harmonization is a statistical term used to describe the process and result of adjusting differences or inconsistencies in data to bring significant features into agreement. In the mySidewalk Platform, this statistical process is used to facilitate comparisons of Census geographies over time.

GIS - Geographic Information System (GIS) is an information system designed to capture, store, manipulate, analyze, and manage spatial or geographic data.  

Goal Tracker - A goal tracker is a data visualization for tracking and displaying progress on the goals your community has set out to accomplish. 

Hex Code - A hex code is a way of specifying a color, starting with a # sign, then a 6 digit number.

KPI - Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively a company, city, or organization is achieving specific business objectives.

Layer - A layer is a dataset in the mySidewalk Platform. We refer to all datasets in the mySidewalk Platform as a layers because all our data is mappable. 

Layer Library -  The user layer library is where all the layers uploaded by your organization for your dashboard will live. Often this tool is also referred to as the “user layer library.” It can be found under the menu then in the tab called “layers.” 

Map Style - Map Style is the term used to describe the "base map" or map underneath your data in the mySidewalk Platform.

Metadata
- Often described as "data about data," metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use or manage an information resource.

Natural Breaks - A method of data classification that seeks to partition data into the classes based on “natural groups” in the data distribution. 

Normalization - Normalization is the process of taking a count and dividing it by something else in order to make a number more comparable or to put it in context. When you normalize data you eliminate the units of measurement for data, enabling you to compare data from different places.

Opportunity Zone - An Opportunity Zone is an economically-distressed Census Tract where new private investments of capital gains will be eligible for tax abatement. Localities qualify if they have been nominated by the state and certified by the Secretary of the U.S. Treasury through the Internal Revenue Service. For more information on Opportunity Zones, check out this FAQ from the IRS.

Pivot Table - A pivot table is a tool that allows you to reorganize and summarize selected columns and rows of data in a spreadsheet or database table to obtain a desired report.

Static Line - A static line is a line on a bar chart or time series often used to display a goal, threshold, or an average. 

Sub-geography - In the mySidewalk Platform, a sub-geography refers to the smaller geography within a larger geography on a map. If you are looking at city data, you might be looking at the numbers for the whole city, or you may be looking at a smaller geography, such as the census blocks within the city. The census blocks in this case would be your sub-geography. 

Tags - Tags are words or phrases that help organize your data layer library. You can add tags to several layers to “group” them together and make searching for them as easier. 

Temporal Data - Temporal Data is simply data that represents a state in time.

Time Element - A time element is used to tell a browser, or in this case, the mySidewalk Platform, that the associated text in a dataset is time-related.

Travel Time - Elapsed time from when an emergency vehicle goes enroute to when they arrive on scene.

Turnout Time - Elapsed time from when an emergency vehicle is dispatched to when they go enroute to the scene of the incident.

URL - A Uniform Resource Locator (URL) is the address of a resource on the internet. 

UTR- User Transformation Request (UTR) is what the mySidewalk team receives when you request assistance with uploading a data layer. The UTR has your original dataset and contains information about the data that you provide.  

WCAG - Web Content Accessibility Guidelines (WCAG) are a part of a series of web accessibility guidelines published by the Web Accessibility Initiative. These guidelines provide a standard for accessible web display. The mySidewalk Platform, including reports, dashboards, and embedded assets, meets the WCAG 2.0 Level AA accessibility guidelines.

90th Percentile Response Time
- The time for which 90 percent of observed response times fall below. The following interpolation methods may be used if the 90th percentile time falls between two observed times, j > i:

  • linear: i + (j - i) * fraction, where fraction is the fractional part of the index surrounded by i and j. For example, the rank order of the 90th percentile in a set of 13 numbers is 0.9*14 = 11.7. So, the “fractional part of the index” surrounded by the 11th and 12th numbers equals 0.7.
  • lower: i.
  • higher: j.
  • nearest: i or j, whichever is nearest.
  • midpoint: (i + j) / 2.

Linear Interpolation Example:

Take the following ordered set of 13 numbers: [1,3,5,6,10,13,16,19,22,23,30,31,40]. The rank order of the 90th percentile is 0.9*13 = 11.7. The 11th and 12th numbers in the series are 30 and 31 respectively. Therefore, using the linear interpolation approach, the 90th percentile is equal to 30 + (31 - 30)*0.7 = 30.7.

Records missing response times are always dropped from the dataset before computing 90th percentiles. 90th percentile Total Response Times and Travel Times are only computed from emergency responses. 90th percentile Turnout Times include all incidents, irrespective of emergency status.
