Frequently Asked Questions

VectorAnalytica’s core products are web and mobile applications for research and decision-making support. Our most recent applications have been focused on public health and epidemiology

Customized means that clients define the functionalities to be installed in the application. VA can suggest features supportive of the overall design but the client may order any desired. changes and can even request a particular functionality not previously programmed

The client owns the data and serves as “data controller” for all app data processing. The data can be hosted on the cloud or on one or more private servers, but only the client handles the data and sets up and controls all access authorizations.

The data are always owned by the client. Upon termination or expiration of the license, the owner should export the data from the VA cloud space to another host. The license agreement will specify authorized use of data by VA during the licensing period.

No, the only information to which VA needs access concerns the specific problem to be solved. In the event the problem to be solved is considered “sensitive information,” VA will sign a non-disclosure agreement. 

A 14-day trial period to test SurveyAppMaker  with MyQueryForm synchronized is available. A trial period for a customized or basic web engine could be made available upon request.

SurveyAppMaker, MyQueryForm, and MosquitoTracker work worldwide at all administrative levels. Settings of the customized Web Engine can be fixed to work from neighborhood block to entire country-level or even larger geographic regions, including arbitrary boundaries as defined by the customer.  

Java language, HTML5, JavaScript, R ( ), Python and Cloud computing

R and Python are free, with a large development community, excellent documentation, and forum. Both have algorithms that are more current than ArcGIS, MapInfo, ArcView or other GIS. Their analytical capability is always in development and they offer many forms of analysis and visualizations.

Our web software uses the security services AWS provides: Network firewall built into Amazon VPC, encryption across all services, DDoS mitigation, data encryption within the database services, authentication using AWS IAM with Multi-Factor Authentication (MFA) using CloudWatch. 

Medium-High level of security is the default security level for  all our web apps. We are ready to implement additional security measures and controls as necessary to keep the data secure and privacy protected.

The mobile apps connect to the services through encrypted channels using TSL. Data on the device is encrypted. MosquitoTracker is public; MyQueryForm is for exclusive use by registered users. MyQueryForm sessions expire after 15 minutes of inactivity. If connectivity is unavailable, any data captured are stored on device. When connectivity is reestablished, users must re-register to synchronize the data. Security levels can be increased as required.

Yes, on standard formats like xls, csv, and pdf for now –but only by authorized users.

Yes, through the web interface or using the API of third party providers such as weather services, census tracts, etc. Also, VA customizes and develops APIs or other protocols to import particular datasets from different data sources as needed.

We offer Platform as a Service (PaaS) with different modules and features on-demand, and depending on the number of users and functionalities requested. For more information, contact us through

Running time depends on various factors such as: quantity of data, type of analysis, variables included in analysis, but in general it ranges from seconds to hours. Our system prioritizes fast and concurrently running algorithms.

For access to SurveyAppMaker to create your own survey form and begin data collection using MyQueryForm, a 15 day trial period after requesting an account is available.
