# Create your analysis
Under NOVA Analytics, location-based weather data analyses can be conducted. This process involves considering historical weather data and making a one-year forecast.
Click on the "NEW ANALYSIS" button, either in the center or at the top right of the screen, to create a new analysis. Next, you need to follow these six steps.
{% stepper %}
{% step %}
#### Setup
In the first step, you need to select how you want to set up your analysis. You can create a completely new analysis, copy an existing one, or upload an existing analysis file.
Select the desired option and press "CONTINUE".
{% endstep %}
{% step %}
#### Type
You can choose between four types of analysis. Depending on how detailed you want your analysis to be, you can select between high level and detailed. In addition to these options, you can perform example analyses for all types. Analysis types are:
Select the desired analysis type and press "CONTINUE".
{% endstep %}
{% step %}
#### Name
In the third step, you can choose a name and project name for your analysis.
By assigning a project name, you can group your analyses together. Select the same project name when creating your analyses to have them listed under the same project. You can access your projects in the analysis overview.
Press "CONTINUE".
{% endstep %}
{% step %}
#### Locations
In the left panel, you can set a name for your analysis location. In the right panel, "Search name/coordinates," you can specify your analysis location. You can select the desired location by clicking on the map, searching for an address, using the current GPS location (if available on your device) or adding a previously created [location asset](/nova/assets/locations-and-routes.md) via the "ASSETS" button. You can also upload a CSV file.
Next, you can choose the altitude at which your analysis should be taken. You can select between 10m (33ft), 152m (500ft), and 305m (1000ft).
Additional locations can be added by clicking the "Add Another Location" button.
Press "CONTINUE".
{% endstep %}
{% step %}
#### Time
Under "Time," you can set the starting point and the time frame for your analysis.
On the left, you can specify your start year, and on the right, your time frame: 1 year, 3 years, or 5 years. For each period, the analysis will be conducted up to the following year starting from the chosen year. Accordingly, a 3-year analysis will consider data from the last two years, and a 5-year analysis will consider data from the last four years relative to the start year.
Below, you can set the time of day to be considered. You can choose between Day, Night, Day & Night, and Custom. For day and night the times are adjusted depending on the time of sunrise and sunset. Under Custom, a specific start and end time can be configured.
Analyses can be conducted that consider data starting from the year 2015 at the earliest.
Click "CONTINUE" next.
{% endstep %}
{% step %}
#### Runway
As part of track analyses, you can specify the runways to be analyzed. To do this, enter the name, orientation, and purpose of the runway (Approach/Departure). You can center the track in the map using the star icon and delete it using the trash icon. If you want to add multiple tracks, you can do so via the plus symbol in the top right corner.
{% endstep %}
{% step %}
#### Track system
In the next step of the track analysis, you can group your approach and departure runways into a track system. First, choose a name for the track system, then assign the previously created runways to the approach and departure sections. You can add multiple track systems using the plus icon or delete them using the trash icon.
{% endstep %}
{% step %}
#### Limits
You can define limits for each analysis type except for the wind analysis.
Under "Accepted Operational Conditions", you can specify the conditions under which your track system may be used. These can be restricted to nominal values or to nominal and moderate values. The exact values can be entered below, next to the units.
In the Service Availability Analysis and Benchmark Analysis, pre-existing limit sets can be added via "Assets." Additionally, through the three-dot menu, you can create or edit these limit sets directly and generate an example limit set.
{% endstep %}
{% step %}
#### Summary
Before starting your analysis, you have the opportunity to review your information in the summary. You will get an overview of your analysis locations with a map, your time settings (year range, time of day), and additional information (data points and estimated duration). Depending on the analysis type, an overview of your limit sets and track systems will also be displayed.
Under "Start Analysis," you can begin your analysis. The completion of your analysis may take a few minutes. Next to it, you can download your analysis setup in .json format.
{% endstep %}
{% endstepper %}
{% hint style="info" %}
Once you have started your analysis, it will be displayed in the project overview. If you cannot access the analysis yet, it is still loading, and a circular loading icon will be displayed.
{% endhint %}
